I think mathematics mainly depends on rational thinking. I like it very much, but I don't like it. So first of all, you should have guidance in this area, such as buying vegetables and letting him count, buying advanced books, not buying questions, and buying popular science; In addition, don't let him learn olympiad from an early age unless he is particularly interested. I think math can still pass the 138 college entrance examination (150 is full). I like doing math problems, but I really didn't like watching them in primary school. So there is nothing wrong with letting nature take its course. It is helpful to exercise logical reasoning and so on. Hope to adopt ~
