Which is more difficult, math or olympiad?

Olympic mathematics is very difficult. Olympiad is much more difficult than math. Many children find it difficult when they first come into contact with the Olympic Mathematics, and there is no way to solve the problem. This is because the study of Olympiad pays attention to the flexible use of mathematical knowledge, and the study of mathematics is often from the shallow to the deep, so that most students can accept the learning process of mathematics more easily and master mathematical knowledge better.
