Primary school mathematics content:
Numbers and algebra mainly include reading and writing methods of numbers (integers, decimals, fractions), rewriting of numbers (turning them into tens of thousands or hundreds of millions of numbers, seeking divisors, etc. ), comparison of numbers (comparison of integer, decimal and fractional sizes), and four operations (calculation rules, operation sequence, operation rules, etc.). ), and the measurement of quantities (quality, length, area, etc.).
Geometry and graphics include understanding graphics (the name of graphics, the names of various parts, characteristics, properties, the relationship between graphics, etc. ), observing objects, calculating the area of plane graphics, the surface area and volume of three-dimensional graphics, the movement (translation and rotation), position and direction of graphics, etc.
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.

They do not exist in nature, but only in human thinking and ideas.
