I have an Olympic math competition, and there are all kinds of computing geniuses in all kinds of programs. Math geniuses are doing a very simple calculation of the number of jobs. Olympiad contest may be relatively more difficult than numerical calculation, and there are some brain teasers, but in the final analysis, these things are all about elementary mathematics. To really think of a great mathematician, only by understanding the research of advanced mathematics can there be a theoretical breakthrough. There is nothing wrong with knowing arithmetic, because no matter how fast people calculate, they can't be as fast as supercomputers. We should do some work that computers can't do, so that we can make progress in mathematics.
In the history of the origin of mathematics, we will find that calculus is a very important part and a very important plate in higher mathematics, but its founders are all from that faction. The times of Lagrange Cauchy and Rolle are basically different, but they all have origins and are rarely independent. Great mathematicians appear, so many teachers should have direction guidance and work out a particularly powerful thing by themselves. A great mathematician means that he has really made his own achievements in the abstract thinking of mathematics, rather than saying that arithmetic is fast, which is nothing.
Mathematics is very important, as a basic subject, some mathematics in our primary school, junior high school and senior high school is only elementary mathematics, the probability theory of calculus that we come into contact with after college, and even the stepping stone of higher mathematics. If you want to really study profound things, you have to read at least a master's degree in mathematics before you can understand them.
