This part of number theory is complicated, so when learning, you should not only remember the basic concepts, but also understand all the related characteristics, which requires you to accumulate step by step.

1, comprehensively sort out the knowledge system of number theory, and let children know fairly well. Please refer to the following brain map for the number theory system.

2. Cultivate children's correct problem-solving ideas, standardize problem-solving steps, and let children develop good problem-solving habits.

3. Help children break through the comprehensive problems of number theory, so that the finale is no longer "stuck".

The branch of number theory:

After number theory became an independent discipline, with the development of various branches of mathematics, new methods of studying number theory appeared. According to the research methods, number theory can be divided into elementary number theory, analytic number theory, algebraic number theory and geometric number theory.

Elementary number theory does not rely on other mathematical disciplines, but only relies on elementary methods to study the properties of integers.

Analytic number theory takes mathematical analysis as a tool to solve the problems of number theory. Solving the problem of number theory by mathematical analysis was laid by Euler, and the Russian mathematician Chebyshev also made outstanding contributions. Analytic number theory is a powerful tool to solve the problem of number theory.
