I hope my reply can satisfy you
2. Or follow the essence of chemical reaction, don't always make equations to solve problems, use the conservation of mass, element, redox electron gain and loss, charge conservation, and other conservation conditions, in addition, the difference method, cross method, is also a simple method of calculation
3. The tenth power computing bank can help edge computing achieve the following functions:
customization, aiming at scene segmentation: different instries have different proction systems, and each enterprise needs its own specific application scenarios. In other words, if you want to land, edge computing needs to be configured according to different conditions and operating environment to support a variety of instry scenarios. Such a set of computing resources can be quickly copied to various places to meet the needs of edge computing. In addition, there are meteorological forecasting, agricultural remote sensing, environmental monitoring, medical image analysis, etc. These customized and subdivided scene computing power output can be realized in the tenth power computing power bank
performance of independent processing chip: usually, after receiving data, edge computing needs to process the data independently. If the chip performance is insufficient, it cannot process. For example, in the smart city scenario, there will be additional demand for computing power and storage in proct design, so the support of GPU card, PCI slot and SSD needs targeted design.

4. How to improve the calculation ability of junior students
[Abstract] calculation is one of the important contents of mathematical knowledge. Calculation ability is a basic mathematical ability, including the accuracy and speed of calculation, which is an important basis for learning mathematics and other subjects. In primary school mathematics textbooks, calculation accounts for a large proportion, especially the low-grade students' calculation ability, which directly affects the students' learning quality, because some concepts in mathematics need to be introced through calculation; The ideas, steps and results of solving practical problems in mathematics should also be implemented through calculation. The mathematics of geometric knowledge involves the calculation of perimeter, area and volume. The derivation and application of formulas are also inseparable from calculation. The knowledge of simple equation, proportion and statistical chart is also closely related to calculation. It can be seen that students' computing ability is crucial. Therefore, to improve the students' computing ability, we should start from the lower grade students and carry out serious and strict training. Only in this way can we help to cultivate students' mathematical literacy, improve students' ability to solve problems, and establish students' quality of being serious, meticulous, patient and fearless of difficulties
[Key words] interest; Strengthen training; calculation; Habits
in junior mathematics teaching, I deeply realize that a child's computing ability is not strong, which will have a great impact on the child's overall mathematics performance, so I attach great importance to the cultivation of students' computing ability in normal teaching. So how to cultivate children's computing ability? I think we should focus on the following aspects of training:
first, adhere to the training, cultivate short-term memory ability
1, master the "within 10, within 20 addition and subtraction", "nine multiplication formula"
junior grade as the key starting stage of Mathematics learning, the introction of addition, subtraction, multiplication and division will have a profound impact on students' future learning. Teaching practice tells us that any complex problem is composed of simple problems. Whether it's multiplication and division of two digits or multiplication of two digits by three digits, or other more complicated calculation problems, their basis is "addition and subtraction within 10", "addition and subtraction within 20" and "nine nine multiplication formula". If these basic knowledge is not up to the standard and can not be blurted out without thinking, and if the "addition and subtraction method within 10", "addition and subtraction method within 20" and "nine nine multiplication formula" are not skillfully mastered, it will not be accurate and fast in the middle and high grades
2. Strengthen the training of oral calculation ability
oral calculation is not only the basis of written calculation, estimation and simple calculation, but also an important part of calculation ability. Only the ability of oral calculation can improve the accuracy and speed of written calculation. In order to cultivate students' computational ability, we should pay attention to the training of oral arithmetic. Both oral and written arithmetic can't do without short-term memory. Some calculation errors are caused by students' short-term memory. Short term memory plays an important role in primary school students' mathematics learning and the development of mathematics ability. Oral arithmetic is the best way to train students' short-term memory ability. Therefore, we should strengthen the training of basic skills of oral arithmetic in daily teaching, Step by step to reach the level of proficiency
the teaching content of lower grades is relatively less. Teachers can use oral arithmetic in class and time children to do calculation exercises, which can effectively improve the students' calculation speed. Oral arithmetic is not only to time, more important is to let children see right and wrong, for those who got full marks in the prescribed time, to give certain rewards, in order to arouse students' attention to oral arithmetic, for the students who made mistakes, also to help find out the reasons, solve problems, stimulate their interest in learning. In addition, pay attention to oral arithmetic is a must do in homework, stick to this work, oral arithmetic ability will be improved< Second, strengthen the calculation ability. Using laws, properties and laws, each algorithm has a certain method, which is the premise of cultivating and improving students' computing ability. Let the students not only know what it is, but also know why it is, so as to improve the mastery level of the four knowledge, and improve the students' ability to strengthen the calculation
1. It is easy to make mistakes in the order of calculation because of students' fixed thinking and not careful examination. Ask students to encounter complicated problems, do not be afraid, calm, calm to see the number and symbol in the problem, determine the order of operation, and then start to calculate
2. Strengthen the memory of special values. Common numbers in calculation should be memorized by students on the basis of understanding, which can greatly improve the accuracy and speed of calculation. For example: the special proct in multiplication -- 25 × 4=100 ,125 × 8 = 1000 and so on
3. Checking calculation is an important measure to prevent errors. There are many ways to check calculation. It is the easiest way to judge the result by estimation. It is true that estimation can only see obvious errors and can not replace calculation and checking calculation. However, the combination of estimation, calculation and checking calculation can improve the efficiency of inspection
4. Simple calculation is helpful to improve the flexibility and agility of students' thinking. In order to improve the ability of calculation and strengthen the skills of calculation, students are required to observe the characteristics of numbers, symbols and formulas, reasonably use the law of operation or the nature of operation, and consciously carry out simple calculation< Third, we should pay attention to the analysis and correction of mistakes.
students' learning is a process of repeated understanding and practice, and mistakes are always inevitable, especially for the lower grade students, because of their age characteristics, the knowledge they just learned is easy to forget. For example: abdication minus, the former abdicated "1", but forget to subtract "1" when calculating. Similarly, when doing carry addition, they forget to carry, especially the addition of continuous carry, subtraction of continuous carry, and more errors of forgetting to add and omitting to write, which are related to children's incomplete memory. Therefore, teachers should timely understand the problems existing in students' calculation, deeply analyze the causes of calculation errors, and carry out targeted teaching
in order to better understand the students' learning situation, we can write comments when correcting the homework, add comments on the mistakes, point out the causes of the mistakes, and let the students know where the mistakes are, whether it is e to their carelessness, or which aspect of knowledge is not good enough. If we know the mistakes, we must do them again, and deepen our understanding of the correct knowledge. Teachers should also focus on the analysis of the reasons according to the human factors. For example, most of the students have made mistakes, they should focus on explaining and analyzing the reasons for the mistakes; For students who have poor foundation and often do wrong questions, teachers should spend more time after class. Students should reflect on the mistakes in their homework. Each student should prepare a book, write down the mistakes in the daily homework in the book, and write down the mistakes and correction methods. In addition, we should take the similar problems of the students' frequently wrong questions as the students' homework, and give feedback again to understand the effect of the students' homework after correcting the mistakes. The practice of correcting wrong questions requires students to judge right and wrong, find out the mistakes, analyze the causes of mistakes and correct them. In the classroom, the "game" method is adopted, such as the form of a little doctor to find the cause of disease competition, so that students can acquire knowledge in the competition“ "Correcting mistakes" can not only satisfy students to distinguish the causes of mistakes and correct them, but also achieve the effect of prevention, and ecate students to correct these mistakes if they have any, and encourage them if they have no< Fourth, cultivate students to develop good calculation habits, which directly affect the formation and improvement of students' calculation ability. Many students can understand and master the algorithm, but they often make mistakes, mainly e to the lack of strict training and good learning habits
to improve students' computing ability, we must pay attention to the cultivation of good computing habits< First, students should form the habit of proofreading carefully. The students are required to proofread the copied topics carefully, ranging from numbers and symbols, so as to make sure they are good< Second, students should form the habit of examining questions. Ask the students to see each number and operation symbol clearly, determine the operation order, and choose a reasonable operation method< Third, students should form the habit of careful calculation and standardized writing. Students are required to write neatly and in a standard format. At the same time, those who can do it should do it orally, while those who can't should do it in writing, so as to strengthen the students' habit of making drafts. In column vertical calculation, the digits should be aligned, there should be proper spacing between the digits, the carry digits should be written in the position, and the number of the exit points should not be less< The fourth is to make students form the habit of estimation and conscious checking. Teachers should give students the methods of checking and estimating, and take checking as an important part of the calculation process to make strict requirements. It is advocated to use estimating to check the correctness of the answers
computing teaching is a long-term and complex teaching process, and improving students' computing ability is not a matter overnight. In the usual classroom teaching, guide students to put forward effective and creative problems that meet the students' knowledge level, and can put forward appropriate mathematical problems from multiple angles and solve them. I think through the accumulated process and unremitting efforts, we will achieve better results. As the saying goes, if you want to develop a good ability, you must "keep your fist and your tune together". As long as there is the joint efforts of teachers and students, it will be effective. This will be the direction of the unremitting efforts of the junior primary school mathematics teachers< br />
