I remember when I was in primary school, I lived in a double class, that is, I was in Class 1 from Grade 1 to Grade 5. One day, when the teacher was giving a lecture to Gao Nian, he wrote "Learn by rote" on the blackboard. I still remember this sentence.

From a scientific point of view, mathematical knowledge points are not only used for memory;

The main reason is that even if you memorize it and remember it, sometimes you just can't remember it.

More specifically, knowledge learning has three levels: (1) understanding. Speaking of it, you just know that you don't need to study further, just listen, as long as you learn; (2) understanding. With the further study, it is not enough to know only how it came from, but also how it came from, that is, "know why, know why"; (3) master. With the further study, you will enter a higher level, that is, you can achieve mastery through a comprehensive study, even if others don't say it.

That's all. It's tiring to sort out the information, but I'm still happy to help you. If you agree, just like it ~
