Specifically, mathematics mainly studies three aspects:

The first is the quantitative relationship. Like algebra.

The second is the spatial relationship. Like geometry.

It also includes the synthesis of the above two relationships. Such as trigonometric functions.

The third is the logical relationship. Such as the judgment of right and wrong.

How to learn?

Mathematics comes from practice. In the study, we should pay attention to connecting with reality, and in the process of thinking and solving, we will learn mathematics with practical problems to be solved, and the effect will be better.
