Multi expression computing power

1. 1. If there are multiple cubes in your cube, then follow the mouse model, use ray on the model, and the cube touched by ray changes (such as color darkening)
2. Draw multiple cubes, arrange them in order, name them, and remove the meshender attribute (no rendering), which is equivalent to drawing a grid, which is easy to understand
3. It's troublesome to judge the range with two-dimensional array (mainly integer), The simple way is that the computer obtains the original coordinates of the model (such as the center point of the model). When the absolute value of the x value (and y value) of the mouse's real-time coordinates minus the original coordinates is equal to the side length of the square, the square (or other dry points) will be displayed with the real-time coordinates as the center, The real-time coordinates are used as the original coordinates for the next step

2. E-coin is a kind of virtual currency born in the Internet, which can support the point-to-point payment function. It is assumed that e-coin can circulate among countries, barter platforms, and enterprises. It is a widely used token that can realize the point-to-point payment through the Internet in the barter process, and has made the "currency" function for the global circulation of the barter instry
the birth of e-coin: e-coin originated in Germany, which is one of the most mature and developed countries in the world trade. It is also the first country to recognize and use virtual currency (bitcoin) and one of the important allies of the United States. In the future, the trend of global virtual currency will inevitably prevail. Germany took the lead in recognizing the legal status of bitcoin, and at the same time launched the global plan of e-coin in time. In the future, global economic integration is also an inevitable trend, and barter instry will graally extend to every corner of the world, so e-coin was born under this inevitable development trend
issue of e-coin: e-coin is issued by research on Social Economic Science (eoses) under the Ministry of finance of Germany. It is planned to issue 6.75 million copies to the world from 2014 to 2017, including 3.6 million copies in the first year, 1.8 million copies in the second year, 900000 copies in the third year and 450000 copies in the fourth year. The total number of issues per year is distributed on an average of 360 days (of which no issue is made on December 27-31 of each year). The circulation in the first year is 1000 / day, 500 / day in the second year, 250 / day in the third year and 125 / day in the fourth year. Due to the limitation of the total amount and the continuous rection of the quantity, with the increasing demand of e-coin graally entering the barter platform in the future, it will lay the foundation for the destined appreciation of e-coin. According to the rough calculation of the total transaction volume of the global barter platform by the eoses experimental group, the highest price of e-coin will be stable at US $10000 and RMB 60000 to meet the demand of barter token circulation. The German Ministry of Finance intends to confirm the legal status of the e-special currency after the price of the e-special currency is stable at US $5000
mining of e-coin: e-coin is composed of 64 base encryption algorithm data. Each coin will be divided into three decimal places at most, and it exists and circulates with the Internet in the form of original code. Every coin needs a computer online to "mine" through the computing power of the computer to obtain e-coin. Because each e-coin has its own code composition, there is no possibility that the issuing institution has a large number of e-coins. Although there are issuing institutions, they are also among the nodes of the Internet all over the world. Moreover, "mining" is limited according to the fixed issuing time of e-coins, and no indivial or organization can obtain more than 51% of the e-coins, Therefore, it not only solves 51% of the risk, but also is a kind of decentralized currency. At the same time, the eoses experimental group issued the e-special currency under the supervision and management of the financial department, which relatively guaranteed the basis for the standardized and stable operation of the e-special currency. The total amount of e-coin issued every day is limited, but it does not mean that the total amount of e-coin issued on that day will be mined out. E-coin is based on the sum of the computing power of all mining computers on that day to determine whether the amount of ore pool is mined out on that day. If the total amount issued on that day is not mined, it will be accumulated to the next day's total ore pool and mined together.

How to learn junior high school mathematics well? What methods should be used

mathematics is a problem that many students are worried about. Many students have certain problems. The score of this subject is very low, so how to learn junior high school mathematics well? Is there any way to improve it

So if you want to learn mathematics well, you need many efforts, which is related to many factors. First of all, you can find your own way of learning, and then understand the characteristics of this subject, so that you can have a certain understanding, and then start to learn. I believe that through this article, you should know how to learn junior high school mathematics well

5. 1、 Cultivating students' ability of mathematical abstraction
the reason why students feel that mathematics is difficult to learn is that they lack the ability of mathematical abstraction. In traditional teaching, the teacher directly tells the students what the abstract conclusion is, but does not let the students participate in the abstract process, leading to rote learning. Therefore, teachers should play a leading role, guide students to observe the essence through the phenomenon, understand the "abstract", and learn to summarize. Let students form their own mathematical proposition, mathematical thinking, teachers to correct and improve, for a long time, students will have the ability to learn knowledge independently< Second, to cultivate students' logical reasoning ability
thinking about every innovation and discovery in human history is inseparable from inction and analogy. In the classroom teaching, analogy is widely used to introce the relationship between the great inventions of human beings and logical reasoning in mathematics, so as to make full use of situational teaching and cultivate students' interest in learning mathematics. This requires students to boldly discover and put forward propositions. Some of their ideas will be new inventions in the near future, that is, axioms of theorems; At the same time, the essence of mathematical reasoning lies in dective reasoning. Famous syllogism constitutes a knowledge system of mathematics. Axioms, theorems and inferences are mostly syllogism. Dective reasoning is the cornerstone of modern civilization. When we tell students the syllogism reasoning mode, let students go to reasoning, grasp the basic form and rules of reasoning, and correctly write the steps of reasoning. Cause and effect are clear, writing has logical order, and the process of exploration and demonstration; Construct the proposition system, at the same time, apply what you learn, and use logical reasoning to solve problems in mathematics and life< Third, to cultivate students' mathematical modeling ability, students are required to discover and ask questions, and use known knowledge to build models; Solving the model; Test results and improve the model. Through mathematical modeling, students' ability to operate and understand knowledge can be cultivated, so as to combine theory with practice. Reflecting that mathematics comes from life and will be applied to life, mathematical modeling is a necessary requirement of the new curriculum standard, and an important embodiment of the combination of theory and practice, so that students can achieve the purpose of learning. In ordinary teaching, students are required to pay attention to collecting models and data, pay attention to classification, and prepare materials for mathematical modeling for a long time< The fourth is to cultivate students' intuitive imagination ability. For example, in the teaching of solid geometry and plane geometry, we encourage students to make their own models first, so that when we show the geometric figures, students will not be unfamiliar with them any more, and they can also find the positional relationship between points, lines and surfaces, which successfully avoids the rigid explanation and achieves twice the result with half the effort. At the same time, students are required to pay attention to observation in life, and form some mathematical intuitive models in their minds to feel the beauty of symmetry and curve in mathematics. Cultivate students' imagination ability, can organically combine number and shape. Therefore, in the process of teaching, we should guide students to view problems from the perspective of imagination, spare imagination, bold imagination, let students open up in the classroom, instead of restricting students with the traditional mode, cultivate imaginative talents in the new era< In general, the algebra part of mathematics is to define addition, subtraction, multiplication, division and related operations on the set to form an algebraic system and related conclusions, which requires students to understand operations, master operation rules, explore operation ideas, and design operation programs for operations. Operation is an important part of dective reasoning, a tool for the inheritance of human civilization, and a means for the cultivation of rigorous and realistic scientific spirit. Let students fully perceive the creativity of operation. Nowadays, many programs are implemented in big data processing. They are all in operation and value taking. Only when they have high operation ability can they recognize these programs. This is the call of the times and conforms to the requirements of historical development< In today's world, cloud computing, big data processing and other rapidly changing achievements are inseparable from data. Today's competition has become the competition of time, capacity and survival of the fittest, which requires students to have the ability of data acquisition, data analysis and knowledge construction. At present, we are in the era of diversified information, which requires human beings to have the ability to process information and data, in order to make computer technology better serve human beings. Usually let students pay attention to data collection, collation, classification, can cultivate students' ability in this aspect, starting from bit by bit, will eventually cast great achievements.

With the price of bitcoin rising to a very exaggerated height, bitcoin also has a high degree of topic. Many people have joined the mining instry, hoping to take advantage of this opportunity to get a share, just as about 20% of Internet cafes in South Korea have closed down to dig bitcoin. However, bitcoin is very power consuming. The daily electricity cost alone is an exaggerated figure< this is because bitcoin mining requires computing power, which requires power consumption. In addition, there are usually multiple mining machines operating in a mine, which makes the power consumption of bitcoin mining a very exaggerated figure

in general, bitcoin mining is really power consuming

7. First of all, you have to train yourself to do right every time you do a question. Check it every time you finish a question. Don't check all the papers again. In this way, your memory of this question is still fresh, and you can easily find some low-level calculation errors. Also, when calculating problems, try to concentrate your mind and don't think about it. While calculating, you can whisper what you mean. In this way, you can force your attention to focus on the calculation and make fewer mistakes. Finally, it's very important to practice more. No matter how good the theory is, it's useless if you don't have enough questions to do the foundation.
good luck

8. 1、 The problem is: (1) research background: in the long-term teaching process, when teachers check students' homework, it is not difficult to find a prominent and thorny problem, that is, the quality of homework is not as good as that of homework in school, which is reflected in: there are several students in each class whose homework can not be completed in time, and many students have poor attitude towards homework, It can be seen from the handwriting that the handwriting is scribbled (far from the words carefully written), and the page is untidy. When doing homework is not very serious, such as speed, not quality, carelessness, perfunctory, daub, writing is messy and dirty, many mistakes. Sometimes, a panic, either the wrong title, or write the wrong symbol. In order to be quick, it's not necessary to do it. Even if you do it, you just grab a piece of paper to do it, or just do it on the cover of a book or exercise book, on a newspaper, or even on a desk or hand. You can't even read it clearly. Sometimes, even if the calculus is right, it is wrong to it in the exercise book. For the students' homework, many rural parents do not pay attention to the students' learning. Whether the students do their homework or not, the parents simply don't care, or just supervise them superficially. As for whether they do it or not, or the quality of it, they don't read it. Some of the students are left behind children, In view of these phenomena, I put forward the research scheme of "Research on effectively improving the quality of rural primary school mathematics homework", hoping to gain something through the research 2 The definition of the topic: "homework" refers to the homework that students finish after class“ "Design" refers to the form and method of operation arrangement, "effectiveness" refers to the actual effect and better effect“ Improve the effectiveness of primary school mathematics classroom homework design "refers to the investigation of primary school students' mathematics homework, and further explore, on this basis, put forward the corresponding improvement measures, so as to get better results 3 The theoretical basis of the project is: 1. According to Gardner, intelligence is multiple, not a single ability, but a group of abilities, including linguistic intelligence and mathematical intelligence. 2. Metacognition theory. Homework for the purpose of cultivating self-management ability of learning can promote the improvement of students' metacognitive ability. The core of metacognitive ability is the ability of self-management, regulation and monitoring of cognitive activities. The enlightenment is: some homework should be done by students independently, which can cultivate students' self-monitoring ability; Some homework can consider the participation of parents and the cooperation of classmates, which helps students form a harmonious interpersonal relationship. 3. The new concept of homework in the new curriculum standard. The homework of the new curriculum is no longer completely attached to the classroom teaching, but an important content to reconstruct and enhance the significance of the curriculum and life. Homework has become the curriculum vitae of students' growth, stimulating their positive emotions, attitudes and values. Every homework has become the growth point of students' growth. Students' attitude towards homework should also become a kind of life attitude, so that students can experience happiness and happiness, distress and hard work in the process of homework 4 Topic demonstration: 1. Literature review of related research: (1) to do a good job in the research on the effectiveness of mathematical homework design is concive to improving teachers' theoretical literacy and teaching practice experience. At the same time, for students, good homework design is a beneficial supplement to classroom teaching, so as to improve students' mathematical ability more comprehensively 2) The research on the effectiveness of homework design is concive to recing students' homework burden, stimulating students' curiosity and observation, enriching students' extracurricular learning life, and cultivating students' ability to find and solve problems. Develop a good habit of learning mathematics actively 3) The research on the effectiveness of homework design can help students actively use the knowledge they have learned, solve some practical problems in real life, form practical operation skills, and do a better job of unity and cooperation with others. 2. The importance and necessity of research: Students' homework is one of the important means of feedback teaching effect, and also one of the important contents of curriculum reform. The purpose of designing indivialized homework is to reform the homework in and out of class through selective, expansive and interesting teaching strategies, so that students can consciously, actively and actively complete their homework. Indivialized homework can effectively stimulate students' learning motivation, and change what they want to do from what they want to do to what they want to do, so as to enjoy the success and happiness brought by homework, and promote the comprehensive and healthy development of students. 3. Research objectives: (1) to build a new homework design system combining basic homework and open homework 2) Through the research, highlight the emotional, explore diversified evaluation methods of homework 3) Through the research, stimulate students' positive emotions, attitudes, values, so as to not only effectively promote students' academic performance. 2、 Process and method 1 Research content: to carry out the special research of "primary school mathematics homework" is to let students "use mathematics" in the real activity scene, so that the mathematics homework is really built on the basis of students' independent activities. Through many aspects of homework design and exploration, let students happily learn mathematics, master mathematical knowledge, more important is to obtain mathematical methods and skills, develop students' intelligence, cultivate innovative spirit and practical ability 2 Research process and methods: 1. Research object: the third and fourth grade students of our school. 2. Research methods: this research is carried out by action research, integrating the following research methods: (1) investigation method: according to the questionnaire made in advance, the students are investigated on related matters, and some experimental conclusions are obtained 2) Observation method: observe the students' behavior reaction to the new homework and evaluation under the natural normal, use descriptive recording method, collect certain facts and basis, and sort them out 3) Experience summary method: through rational inction of the facts and basis in the process of research, the partial and personalized experience will be upgraded to the principle knowledge with universal significance 4) Case study method: select 1-2 representative students in the class to conct a comprehensive, systematic and continuous observation, and record their development and changes according to the time process. 3. Research process: 1. Formation stage: (March 2011 - April 2011) (1) investigate and analyze the quality of three-year primary school mathematics homework, and do the pre-test work well in advance 2) To collect a wide range of literature on improving the quality of primary school mathematics homework 3) Draw up the project implementation plan, ask experts for guidance, and declare the project. 2. The implementation stage (June 2011 - June 2012) (1) according to the research plan, the third to fourth grade students' attitude towards homework was investigated, and through the research, the students' attitude towards homework was corrected Completion time: September 2011) (2) investigate the evaluation methods of fourth grade mathematics teachers on homework, rectify the problems in the evaluation, and improve the design ability of teachers' homework Completion time: March 2012) (3) combined with the research, to find effective methods and ways to improve the quality of rural primary school mathematics homework. Using the results of the research to improve the quality of decimal mathematics homework Completion time: April 2012) (4) one reading essay, teaching case and ecational story every month. In the process of research, the reading notes should be no less than 40000 words, the topic blog should be established, and the research progress information, learning and research experience should be published in time Completion time: along with the whole research process) establish the management system of primary school students' homework quality (completion time: May 2112) 3. Specific implementation content: specific month implementation content remarks: March to April 1, 2011. Understand the current situation of students. 2. Learn relevant theoretical knowledge. 3. Develop and adopt research programs. September 1, 2011, homework assignment method and effective feedback mode. 2. Communicate with parents and guide them to correct homework for their children. In November 2011, the teacher taught the students the method of self-examination. December 1, 2011, the implementation of the comparison, for the implementation of the scheme before the comparison, find out the deficiencies. 2. Stage summary. In March 2012, we explored the target. In April 2012, checking the feedback of homework in time can greatly promote the cultivation of students' good habits. In May 2012, students' homework was displayed. In June 2012, we summarized, accumulated experience, wrote papers and promoted good practices. 4. Summary stage: (may 2012 to June 2012) according to the research content, collect, sort out and classify the materials, synthesize the research materials, and make a comprehensive and scientific summary of the subject, mainly focusing on typical cases and papers. Write the Research Report and research work report, put forward the application for the end of the project, and complete the paper "basic methods and ways to effectively improve the quality of rural primary school mathematics homework". 3、 There are dozens of students in the class. Their intelligence is high or low, their ability is good or bad, and their foundation is not on the same level. When assigning homework, if it is uniform, it will not show personality. Homework is too abstruse, which is harmful to students' self-confidence. It will make them fear mathematics because they can't taste the joy of success, which is not concive to the teaching and transformation of poor students; Homework is too simple, for excellent students, it is a waste, will make their level stagnant. How can we satisfy both excellent students and poor students? When I assign homework, I add a "one question a day" on the basis of the required questions. For example, for students with poor foundation, I add several basic questions for them to complete each homework. I train them from the simple to the deep, so that they can taste the joy of success and become interested in mathematics; For the students with excellent performance and quick thinking, add several additional questions with certain difficulty to train their thinking. 2. The new curriculum of designing practical homework advocates students to actively explore, obtain information, innovate knowledge, and cultivate the ability to analyze and solve problems. Teachers should combine mathematics with practice when arranging mathematics homework. For example, let them go to the supermarket to experience the weight of objects, deepen their understanding of gram and kilogram, buy things by themselves in the market, and deepen their understanding of RMB, At the same time, in the process of calculation, it improves the calculation ability, goes to the factory to investigate some data, and deepens the cognition of statistical knowledge... All these are concive to the improvement of students' interest and enthusiasm in homework. 3. To cultivate good homework habits, teachers should teach them homework habits, supervise their homework habits and attitudes, so as to promote them to develop good homework habits. After correcting the homework, ask the students to do the wrong topic again to strengthen the knowledge they have learned. 4. Family school combination, cultivate students' learning responsibility, come up with a variety of ways to get in touch with their families after class, and tell them the homework of the day, so that they can have a better understanding

9. 1、 First of all, we need to change our ideas. Junior high school stage, especially junior high school third grade, through a lot of practice, can make your performance have obvious improvement, this is because junior high school mathematics knowledge is relatively simple, easier to master, through repeated practice, improve the proficiency, can improve performance, even so, some problems are not deep enough to understand or even do not understand. For example, in junior high school, when you ask | a | = 2, what is a equal to? Very few people make mistakes in the senior high school entrance examination. However, after entering senior high school, the teacher asks, if | a | = 2, and a < 0, then what is a equal to. Even students who are usually good at learning, some students will answer without thinking: a = 2. That's enough. High school mathematics is highly theoretical and abstract, so we need to work hard on the understanding of knowledge, think more and study more. 2、 The characteristics of high school mathematics are: Thinking reasoning, memory, operation 1, memory: some students think that mathematics is to do more questions, memory is a matter of liberal arts. In fact, there are many contents in mathematics that need to be memorized, such as definition, formula, theorem, axiom, typical method, key question type, knowledge network, etc. To learn mathematics well, we must take out a certain amount of time and energy to remember! But this memory can not be realized simply by reciting and reading several times. The memory of mathematical problems must be realized by thinking, solving a certain number of exercises, reasoning and summarizing. If we don't remember the basic knowledge formula, theorem and problem-solving method, or if we don't memorize them skillfully, it will lead to the slow speed of problem-solving, and even the test can't be finished. There is a phenomenon that the usual homework is well completed, and the test results are always unsatisfactory. This is closely related to the poor memory. Therefore, to learn mathematics well, we must first learn to remember and think. 2. Thinking: the most important thing to learn mathematics well is to learn to think and reason. Students who can't think and reason will never learn and can't do well in mathematics. Mathematical knowledge is like a chain. If one link is broken, the whole chain will be broken. If we can't think and reason reasonably, this chain can't be linked, and it's inflexible or even impossible to start. When we enter high school, we will soon learn trigonometric function. There are more than 30 trigonometric function formulas. These formulas are closely related and complement each other. If we can remember some of the main formulas, we can dece dozens of other formulas through reasoning. Otherwise, memorizing them by rote will bring us a great burden, and the effect is not necessarily good. To learn thinking and reasoning, these formulas are not difficult to remember. In high school mathematics learning, a small number of exercises can be directly substituted into the formula and solved reasonably. Most of the exercises can only be solved by reasoning the basic knowledge. If you don't know how to reason or are not good at reasoning, you can't solve the general mathematical problems correctly. Let me give you a familiar example. Xiao Li and Xiao Wang ran the 100 meter race. When Xiao Li reached the end of the track, Xiao Wang just ran to 95 meters. The second time Xiao Li stepped back 5 meters and ran with Xiao Wang again, who got to the end first? This example seems very simple, but it is easy to make mistakes and fall into the thinking trap if we blindly solve it. So, if you don't think and reason, the simplest problem may also embarrass you. Learning to think and reason is the key to solve high school mathematics problems accurately and efficiently. 3. Operation: in order to improve mathematics scores and test paper scores, it is necessary to improve operation ability. There are many students in the answer to the math questions quickly, clear thinking, and even happy after the test, think the question is not difficult, the result score is very low. Most of the reasons are poor computing ability Its poor computing ability refers to: the computing method is not simple, the computing steps are not standardized, accurate, scribbled, etc.) to improve the computing ability, we must work hard to temper ourselves: 1. Finish the homework assigned by the teacher on time, do not , do not delay; 2; (2) strictly require the steps to solve the problem. Generally, it is better to be more detailed; (3) seriously consider the method of solving the problem and find a simple way of calculation; (4) the writing should be neat and regular. Don't Scribble; (5) reasonable use of draft paper, do not scribble... 3. Specific methods of learning high school mathematics. 1. Preview: preview is very important. Through preview, we can understand the basic content and knowledge to learn, and master the knowledge network of this section, so as to find problems that we do not understand and do not know. Then when listening to the teacher's lectures, we not only have a sense of advance, but also focus on them, It is much better to listen to the teacher one by one and find the problem again than to listen to the teacher directly without preview. In addition, through preview can exercise their self-learning ability, and can grasp the initiative of listening. Some students will feel very passive when they listen to the teacher's lecture without preview. Every time the teacher talks about a question, the students will react actively below. When you are slower than others, when you finish digesting the question, the teacher often starts to talk about the second question. No matter how much you react to the first question, you have to put it down and listen to the second question, Otherwise, you will not understand some questions clearly or completely. If we preview in advance, we can avoid such problems. Therefore, the difficulty found in the preview is the focus of the class; In order to rece the difficulties in the process of listening, we can make up for the old knowledge that we have not mastered well in the preview; It is helpful to improve the thinking ability. After preview, you can improve your thinking level by comparing and analyzing what you have understood with the teacher's explanation; Preview can also cultivate their own self-learning ability. Preview before class is a good learning habit. I hope you can pay more attention to it in the future. 2. How to listen to the class: on the basis of preview, it is very important to listen to the class well. First of all, we should do a good job of material preparation and spiritual preparation before class, so as to avoid the phenomenon of losing books and books in class; Before class should not do too intense sports or reading books, fierce argument, etc. So as not to gasp or not calm down after class. The second is to listen attentively. Concentration is the whole body into the classroom learning, ear to, eye to, heart to, mouth to, hand to
listening: listening attentively to the teacher, how to teach, how to analyze, how to summarize, in addition, listening to the students' questions and answers, to see if they are inspired. Eye to: is to listen at the same time to read textbooks and blackboard, to see the teacher's expression, gestures and demonstration of experimental action, vivid and profound acceptance of the teacher's ideas. Heart to: is to think hard, keep up with the teacher's mathematical thinking, analysis of how the teacher is to grasp the key, solve problems. Mouth to: is under the guidance of the teacher, take the initiative to answer questions or participate in the discussion. Hand to hand: on the basis of listening, seeing, thinking and speaking, it is to draw out the key points of what you have learned, and write down the main points of the lecture and your own feelings or opinions with innovative thinking. If you can achieve the above "five to", you will be highly concentrated, and all the important contents learned in the classroom will leave a deep impression in your mind. In preview, what we accept are superficial and superficial, such as definitions, theorems, formulas, etc. they are all concrete and memorable things, and we only have some perceptual knowledge of the knowledge to be learned. Only through further explanation by the teacher, can the preliminary knowledge be raised to a higher level and become rational knowledge. The demonstration, overturning process and application of the learned knowledge can be clearer, so as to deepen the understanding and memory, and improve the ability of analysis and application. (that is to say, you may recite theorems, definitions and use formulas after reading them, But it is difficult to apply argumentation and analysis to exercises.) the key point of listening is to solve this problem, and to have a comprehensive understanding of theory, analysis and application. Therefore, listening is very important. You must listen with questions and key points, record the key points, and remember what you don't know about preview, Otherwise, it will affect the efficiency of recording and the effect of listening. Some students are easy to think, so, don't think about extracurricular problems, don't ask any questions in the teacher's lecture, interrupt the teacher's lecture, and seriously think about the teacher's questions and actively answer them. Pay special attention to the beginning and end of the teacher's lecture. At the beginning of a teacher's lecture, he generally summarizes the main points of the previous lesson, points out the content of this lesson, and links the old knowledge with the new knowledge. At the end, he often sums up the knowledge of a lesson, which has a high degree of generality and is the outline of mastering the knowledge and methods of this lesson on the basis of understanding. If we want to grasp the logic of thinking, analyze problems and solve problems, we can draw inferences from one instance and improve our ability of thinking and solving problems. In addition, we should pay special attention to the tips in the teacher's lecture. Teachers often give some language, tone, or even some action tips to some key and difficult points in their lectures
3. After class summary: for each lesson taught by the teacher, we must use the self-study of the day to summarize, sort it out in a special notebook, and carefully review and summarize from the definition, theorem, formula, demonstration process and typical examples, so as to form a systematic chain. After class summary, we can find problems, timely record them, and use the self-study of the day to ask the teacher, Try to solve the problems on the same day, otherwise the problems will accumulate, and you will step into the ranks of poor students. In fact, our original poor students are formed in this way. Secondly, the summary itself is not only a reasonable thinking process, but also a kind of repeated memory. At the same time, it has a higher level of understanding. Therefore, the process of our summary is the process of practice -- Understanding -- Re practice -- re understanding. The students who are good at summarizing and doing are generally proficient in basic knowledge, and they are familiar with some basic knowledge in the examination Basic questions can be done quickly and accurately. In the current college entrance examination mathematics, more than 60% of the questions are directly answered through basic knowledge (that is, using definitions, axioms, theorems, formulas and images), which accounts for about 100 points. Therefore, a good summary after class is the key to firmly grasp the basic knowledge. 4. How to deal with homework: homework is an exercise process for students to consolidate, proficient and improve their basic knowledge. Without this process, no matter how clear and profound you look and listen, it's often a piece of paper. Without sufficient homework training, you will not be able to achieve a certain degree of proficiency, let alone dexterity. The so-called "practice makes perfect" means that only on the basis of proficiency can you find some simple and ingenious ways to solve problems and solve comprehensive problems, that is, the so-called ability improvement. Some students can't do comprehensive problems (that is, the so-called "difficult problems") or even can't do it, which is directly related to their lack of proficiency (that is, less problems). Therefore, more practice can make you mature and mature can make you skillful There is no problem with the sea

10. Translate what you described. There's a project called cattle play. The money they issued is called not, and the total amount of money issued for the project is 10 billion. The foundation was registered as the main body of the project in Singapore. That's what you mean. This is a normal blockchain coin issuing project. Whether it's true or false, it can't stop him from making money.
