The definition of mathematics is the most difficult to learn, because different people have different understandings of mathematics. Mathematics covers algebra, geometry, function, equation, definite integral, differential, etc. Mathematics is a discipline that pays attention to logic. Mathematical logic focuses on putting mathematics on a solid axiomatic framework, and mainly studies the results of this framework.

In the process of learning mathematics, children need to strengthen their independent thinking ability, that is, use more brains, do more problems and practice frequently. Mathematics is rigorous, its answers are rarely open, and the most difficult things to learn are inconclusive, because it contains too much knowledge and is too complicated.
