5. Computing power is a concept put forward by NVIDIA when it released CUDA (Compute Unified Device Architecture, a programming language for GPU, similar to C programming for CPU). Because the graphics card itself is a floating-point computing chip, it can be used as a computing card, so the graphics card has computing power. Different graphics cards have different computing power. In order to show the difference, NVIDIA put forward the corresponding version of computing power x.x on the procts of different periods. Computing power 1.0 appeared on early graphics cards, such as the original 8800 ultra and many 8000 Series cards, as well as Tesla C / D / s870s cards. Cuda1.0 was released corresponding to these graphics cards. Today, computing power 1.0 has been eliminated from the market. Then there was computing power 1.1, which appeared on many 9000 Series graphics cards. Computing power 1.2 appears together with GT200 Series graphics card, while computing power 1.3 is proposed when upgrading from GT200 to GT200 A / b revision. In the future, there will be computing power 2.0, 2.1, 3.0 and other versions. The latest released version is computing power 6.1, which is supported by the latest Pascal architecture graphics card. At the same time, CUDA version is also updated to cuda8.0
ordinary users do not need to care about the computing power of the graphics card, only GPU programmers care about this problem when they write CUDA programs to develop GPU computing. As long as you know the model of your computer's graphics card, you can find the corresponding computing power https://developer.nvidia.com/cuda-gpus .

6. The premise of this sentence is "computer ability". This sentence is equivalent to that human beings are inferior to calculators in computing power. This is obvious. People can also calculate, but the accuracy and speed are not guaranteed
Where is the ability of computer compared with human? Fast speed, no fatigue, no rest, no error in calculation, which is beyond people's reach. The computer is programmed by human. The operation of these programs is repetitive and the workload is huge. People can do this, but it is time-consuming and labor-consuming, and the accuracy is difficult to guarantee
for another example, the calculation of missile trajectory has reached tens of thousands of times, but only dozens of formulas and calculation methods need to be used. Using the computer to set dozens of calculation formulas and input different numbers can make accurate calculation.

7. Buying exercises < br > students' poor computational ability is a combination of many factors. If parents want to improve their children's computing ability, they need to make them more diligent. Parents can buy some calculation exercises in the bookstore. Parents stipulate how many exercises their children should do every day. After that, parents should check in time< Br > the main reason for children's poor calculation ability is that they are lazy. After mastering the nine nine multiplication tables, the children do not practice the formulas of these tables, which leads to poor calculation ability. Students can only improve their computing ability through the day after tomorrow's practice< Br > do homework independently < br > some children will choose to use the computer when they encounter some difficult calculation problems. When parents find these problems, they should stop the children's behavior in time. No matter how difficult the calculation is, these children need to calculate by themselves. If it's beyond the children's ability, parents can teach these children how to calculate in advance< When children do homework, parents should play a leading role and supervise their children to finish homework independently. Some children in order to be able to quickly complete the homework, will search through the Internet to find the answer, and even some students copied other people's homework from childhood, parents need to stop these children's behavior in time< How can parents improve their children's computing ability? Parents need to find out why their children are poor at calculating. Some children are e to their lack of practice, some students do not master the correct method of calculation. If parents find out the cause of their children's poor calculation ability, they need to give timely guidance to these students, so that their children can learn the correct calculation method as soon as possible.

10. 1、 Thorough understanding of calculus
calculus is the basis of mathematical calculation, and all mathematical calculations are carried out on the basis of calculus. Therefore, to cultivate students' computing ability, the first thing is to let students understand the calculus of mathematical calculation. The so-called calculation principle is the principle of mathematical calculation. The rule of mathematical calculation is addition, subtraction, multiplication and division, which is commonly known as the four arithmetic operations. It is the basis of mathematical calculation, and the basic arithmetic of the four arithmetic operations is the decimal principle and the borrow principle. If students can understand the operation rules in the four arithmetic operations, their calculation ability can be improved at once, and they will not find it difficult to learn mathematics
however, many math teachers often ignore the explanation of the four operations when they teach them, and even some teachers feel that the simple four operations are not worth spending valuable classroom time to explain. As everyone knows, for the second grade pupils, if the students can not understand the mathematical theory, it will cause difficulties in learning more advanced mathematical knowledge in the future, and eventually lead to the failure to improve their mathematics performance. For the explanation of the four operations, some teachers often simply explain their meaning, just let the students remember this principle: if two numbers add more than 10, one digit forward will be carried forward; if they can't subtract, one digit forward will be borrowed. Because in the teacher's mind, this explanation is very clear, students should be able to understand. But the actual situation may be that the teacher has just explained, but the students still can't do the calculation. The problem is not that the teacher didn't explain it clearly enough, but that the students didn't understand the arithmetic at all< At present, the situation of students' mental arithmetic ability is not optimistic. Especially in the situation that there are more and more mathematical calculation tools and their functions are more and more complete, today's students rely more and more on mathematical calculation tools. Many schools even began to teach students to use mathematical calculation tools when they were in the second or third grade of primary school, and the convenience and speed that students feel when using mathematical calculation tools also easily make them feel dependent, So as to give up doing it yourself. This is extremely serious harm to primary school students, their mathematical calculation ability will only get worse and worse
to solve this problem, we should not only prohibit the use of mathematical calculation tools in the lower grades of primary schools, but also pay special attention to the cultivation of students' calculation ability. After students master the written calculation, teachers should start to cultivate students' mental calculation ability. Mental arithmetic can be said to be an advanced level of calculation ability after written arithmetic. The cultivation of mental arithmetic ability is essential for improving students' calculation ability. The higher the students' mental arithmetic ability, the stronger their ability to accept numbers, and the faster and more accurate mathematical calculation will be
e to the high requirements of mental arithmetic for students' numerical sensitivity, it will be difficult for sophomores at the beginning, but this difficult process is an important process to cultivate students' computational ability. Mathematics teachers can do it 5 minutes before class. At the beginning, they can choose four simple operations within 10, and then slowly improve the difficulty. The training of students can also be carried out one by one according to the seat order, so that each student can get exercise
this way of cultivating students' mental calculation ability may not have obvious effect in the short term, but in the long term, students' mental calculation ability and overall calculation ability can be significantly improved. In addition, students can also be asked to try to solve any mathematical calculation after class< Third, enhance the ability to understand the connotation of numbers
the improvement of mathematical calculation ability is not only reflected in the accuracy and speed of students' mathematical problems, but also reflected in the students' ability to understand the connotation of numbers. The connotation expressed by numbers in different environments will be different, sometimes beyond the connotation of the simple number itself. At this time, it is extremely important for students to understand the connotation expressed by numbers correctly
for example, there is a math problem like this: the elder brother is 4 years old, and the younger brother is half as old as the elder brother. When the elder brother is 100 years old, how old is the younger brother? Among the students, my younger brother is 50 years old. In fact, the root cause of this kind of error is not that students make mistakes in calculation, but that students do not understand the real meaning expressed by numbers, because sometimes what numbers represent is not the real connotation of mathematical calculation and can not be solved by mathematical calculation alone. Of course, this is also related to the cognitive ability of the second grade pupils
mathematics teachers should pay attention to the cultivation of students' digital cognitive ability, try their best to avoid the mistakes of digital cognitive connotation, so that students can have a better understanding of future mathematics learning. Only in this way, students' mathematical understanding and computational analysis ability can be improved.
