Olympiad is a double-edged sword. If you use it well and learn well, you can train logical thinking and cultivate children's good acceptance, thinking speed, depth and breadth. However, if you engage in sea tactics, get quick success and instant benefit, and don't learn Olympiad by methods, you will get sick and lose interest in mathematics. In addition, there is no clear boundary and evaluation standard between the Olympic math problem and the math problem in the classroom. If the problem is simple, it is impossible to select and train outstanding talents and exercise the thinking quality of the brain. At the same time, we should follow Scientific Outlook on Development and let different children have different development in mathematics (the guiding ideology of the new curriculum standard). Therefore, the same is true of Olympic mathematics, and different children should have different development in the thinking level of Olympic mathematics. Finally, there is no Olympiad in the world, and the scientific standard is competition mathematics, which is an extension of school mathematics.
