7. Arithmetic: The abstract includes basic operations such as addition, subtraction, multiplication and division, as well as the concepts and operation rules of integers, decimals and fractions. Through the study of these basic arithmetic knowledge, children can master the basic skills of mathematics and lay a solid foundation for further study.

8. Algebra, abstraction involves the basic concepts of algebra, such as letters representing numbers, algebraic expressions, equations and inequalities. This knowledge helps children to understand the laws of algebraic operation and cultivate abstract thinking ability.

9. Mathematicians usually discover a theorem by intuition first, and the result is specious to him first, and then he sets about making a proof. -Hardy

10, in mathematics, it is very important to distinguish what is important and what is not important. Hironaka Heisuke

1 1. Mathematics is a deductive knowledge. From a set of postulates, we can draw a conclusion through logical reasoning. Chen shengshen

Mathematics is a universal means for human beings to strictly describe and deduce the abstract structure and mode of things, and can be applied to any problem in the real world. All mathematical objects are artificially defined in essence. In this sense, mathematics belongs to formal science, not natural science. Different mathematicians and philosophers have a series of views on the exact scope and definition of mathematics.
