Mathematical problems can be classified according to many different standards. For example, according to the content of the problem, it can be divided into geometric problems, algebraic problems, statistical problems and so on. Or classify the problems according to their solutions, such as direct method, reasoning method, trial and error method, etc.
The classification of mathematical problems is of great significance. By studying and accumulating the classification of mathematical problems, we can better understand and master mathematical knowledge, improve the ability to solve problems, and think more constructively about unknown mathematical problems, thus improving the learning efficiency and the accuracy of solving problems. At the same time, the classification of mathematical problems also has the value of guiding teaching and examination propositions.
