You learn mathematics to learn philosophy, and there is no foundation (sweat), so as long as you learn the logical thinking of mathematics, you don't have to learn the application of mathematics, and elementary school doesn't say it; Geometric proof, algebraic thought and proof, vector and coordinate frame system, function thought in middle school, as long as simple functions are difficult to learn, I can't remember anything else in middle school; College mathematical analysis, advanced algebra, discrete mathematics, mathematical logic, college is more difficult, you just need to learn the main ideas; If you want to strengthen logical thinking, read books on algorithms. I study computers, and I think algorithms are an art (haha). The class A math I introduced (college part) is difficult to learn, and the others are not, but the effect is not good. There is another one. Can you play chess? Chess is good for thinking exercise. When you finish college mathematics, you will feel that the thinking of other subjects is very simple, and so is the computer. If you are not a genius, it will only take one or two years, and the main university part will not be in-depth and in-depth, so it will be difficult for you in this life!

I wish you success in your studies. I think math is not bad. If you have any questions, you can email me: lindytem @ 126.com, and I'll take a look at them when I have time, but I can't remember many of them for a long time. Don't push me-hehe, I have an answer for you, not for your score, but because I can't stand it and see your question.
