2. There are too many levels of difference between the basic knowledge of primary school mathematics and the Olympiad, which is of no reference value. Don't study with the mentality that you can learn Olympiad well by learning the basics, but experience mathematical thoughts with your heart. Second-rate players recite the chess score, and first-rate players write the chess score, that's all.
3, in fact, there is no need for everyone to delve into this thing, but it is really helpless in China. The game with the strongest sense of mathematics is to calculate 24 points with cards. Basically, this game is really fun, and all the little things in the primary school Olympics are there.
Generally speaking, the greatest advantage of children with good liberal arts is that they are good at remembering, but this is only very unimportant in mathematics. Remember things, to a large extent, lost the ability to expand. The most important thing in mathematics is analysis. To put it bluntly, it is why we should take such a road to achieve what we want according to these known conditions. The higher level is to be able to solve a certain kind of problems by mastering formulas and methods, while the highest level is the state that Gauss reached when he was 8 years old, looking for the most suitable laws and methods for different problems.
5. As for teachers, generally good Olympic math teachers don't teach conventional mathematics, and the difference between the two models is too great. As my junior high school math teacher said, only idiots insist on teaching and let students practice elementary arithmetic. To a large extent, the Olympiad only belongs to people with outstanding computing ability, unlike many of my classmates who can do most math problems orally and don't need draft paper for exams. In the world of Olympic mathematics, teachers have two most important missions. One is to tell you that there is such a way to solve this problem, and the other is more important to guide you to keep thinking about mathematical problems and cultivate your own mathematical thinking mode. Anyone's knowledge is limited. You can't let pupils use permutation and combination equations to solve array problems in primary schools. It is important for children to use limited knowledge to solve existing problems by changing angles and combinations.
6. If you study science in the future, there is indeed a big gap between those who learn olympiad well and those who don't.
7. The effective means of short-term promotion is always the sea of questions. In the long run, the sea of questions is also the chief culprit in destroying one's interest and expanding one's thinking ability.
