I don't agree with upstairs. In principle, high school mathematics competitions do not involve advanced mathematics. I remember Teacher Li Chengzhang said, "If a competition problem is solved by advanced mathematics, it is a smelly problem. If it can only be solved by advanced methods, it is the smelly problem in the smelly problem. "

Generally speaking, the final questions of senior high school mathematics competitions are divided into four parts: number theory, geometry, algebra and combination.

Number theory pays more attention to the divisibility of integers and the properties of prime numbers, and geometry is generally plane geometry. The scope of algebra is mainly series and inequalities, which account for at least 90% of all algebraic problems. Combinatorial problems are difficult to define, generally referring to some miscellaneous problems, which are biased towards the nature of mathematical games.

Among them, only inequality is related to the content of higher mathematics, and other contents have little to do with higher mathematics.
