Why would I say that? Because I believe everyone knows what is the most important thing in learning mathematics. The most important thing to learn mathematics in the learning stage is for the college entrance examination and the senior high school entrance examination. You are good at math, and your total score is basically not bad. Therefore, to learn math well, you can go to a better high school and a better university first, which means that you can have better choices and better jobs in the future. Secondly, studying mathematics can also cultivate your various abilities.
For example, your math ability, your spatial ability. If you encounter some unsolvable problems in your life, you can use your math ability to solve them. If he doesn't study math, I believe he doesn't even have any computing ability in society and can't do accounts at all. He may be cheated by others, but you won't have such trouble if you learn math well. Finally, I think the most important thing is that you will become more rational and logical in the process of learning mathematics.
This will be of greater help to your later life. When you think about problems, including solving problems and getting along with people, you will lead you to a better direction and life with reason and logic. Therefore, it is actually necessary to learn math well, not to say that math is not helpful to life, not like this. On the contrary, the ability that mathematics brings you is often hidden.
