Mathematics Curriculum Standard for Compulsory Education develops the "two basics" in mathematics teaching into "four basics", that is, in addition to "basic mathematics knowledge" and "basic mathematics skills", it adds basic mathematics thoughts and basic mathematics activity experience. So, what is the basic idea of mathematics?

The basic idea refers to the idea on which the emergence and development of mathematics depend; Thinking ability after learning mathematics (the thinking difference between those who have studied mathematics and those who have not studied mathematics).

There are three basic ideas of mathematics: one is the idea of mathematical abstraction, the other is the idea of mathematical reasoning, and the third is the idea of mathematical modeling.
