1, some Olympic math problems (typical problems) can broaden thinking, but most Olympic math problems pay too much attention to skills and epiphany and fail to follow the development process of human thinking. Poor study will affect learning confidence and interest.
2. Olympiad will make people develop some thinking habits of digging for details and finding skills, which will affect the formation of the overall knowledge. The blocks of mathematics learning are a series, and there are many horizontal and vertical connections. We should use our brains in this big pattern.
3. The practical use of the olympiad is not great. The guiding ideology of "National Basic Education Mathematics Learning New Curriculum Standard" includes: learning useful mathematics and attaching importance to its application value. China has won numerous prizes in the International Olympic Games every year, but no one from China has ever won the Nobel Prize in Natural Science. This is the best example.
4. Many things of Olympic Mathematics will be found in textbooks with the growth of grades, such as series (high school) and permutation and combination (junior high school and high school).
