Elementary school math, I saw a very simple thing in his house. The teaching methods of mathematics in China are different from those in European countries such as Britain. We pay more attention to the sensitivity of numbers, that is, the fast calculation of addition, subtraction, multiplication and division, but they pay more attention to students' understanding of mathematical knowledge and the construction of a kind of thinking.

If we simply talk about the arithmetic ability of numbers, our well-deserved 1 primary school students even say that a fifth-grade child in our country is more sensitive to mathematical numbers than those in European countries like Britain. What they say, those foreign students, they need to use calculators, and they can't even understand them once, because they don't pay much attention to the addition and subtraction of numbers, and they think this thing is of little significance. They pay more attention to the cultivation of mathematical thinking. How should they learn to understand the essence of mathematics when they study it?

Is this digital computing ability important? It is important in theory, but it is not important either. The important thing is that it is a foundation. The important thing is that mathematics has developed to a certain extent, and these basic addition, subtraction, multiplication and division are no longer needed. Because even doctoral students have a strong professional field, that is, when you study advanced mathematics in colleges and universities, you can calculate addition, subtraction, multiplication and division at a glance, all of which are symbolic operations. That is the application of mathematical logic thinking. Poor mathematical thinking. No matter how fast you can add, subtract, multiply and divide, it is still difficult for you to get a high number in college.

Moreover, no matter how fast a person can calculate, can a computer be fast? After the computer sets the program, the input number will automatically produce the result, there will be no mistakes, and the calculation is much faster than that of people. Fast calculation can only be said to exercise the agility of thinking, thinking faster and having stronger mental arithmetic ability. However, those countries in Europe and America do not pay much attention to the rapid calculation of numbers for learning advanced mathematics and more complicated math homework. So in everyone's eyes, mathematics is weak, but it is not. People may have studied advanced mathematics in high school, but we didn't learn it until we went to college.
