Why do you want to focus on mathematics?

Personally, I think there are the following reasons

1, mathematics is closely related to daily life, and many practical problems in life are related to mathematics. For example, simple addition and subtraction, regression function to predict market changes and so on.

2. Mathematics is closely related to other disciplines, and it is the basis of studying physics, chemistry and other disciplines.

3. Mathematics can exercise people's logical thinking ability, make people smart and improve their IQ.
