It is necessary to pay more attention to learning methods. Mathematics learning should not only include addition, subtraction, multiplication and division. If calculation only forms pure memory in the brain without understanding the logical relationship, it will only become more and more difficult.

With the continuous updating of primary school mathematics textbooks, the content is no longer a simple arithmetic problem of addition, subtraction, multiplication and division, but a lot of daily operations are added to primary school knowledge, which increases the difficulty of primary school mathematics performance to varying degrees.
