Mathematics is one of the main courses in primary and secondary schools, and it is also the basis of physics and chemistry courses in middle schools. Therefore, from the first day of school, their math scores have been highly valued by parents and teachers. Especially in primary school, children's mathematical ability is often used as the main basis and standard to evaluate their intellectual development. However, in school, because there are dozens of students in a class, teachers can only focus on the improvement of all students' mathematics level in classroom teaching according to the basic requirements of primary school mathematics syllabus, closely following the contents of primary school mathematics textbooks. In this way, for some "top math students" who have good math scores and spare capacity for learning, they feel "not enough to eat", which hinders the development of their math talent. Mathematics competition is to meet the needs of these "top students in mathematics" and provide them with a big stage to learn and compete in mathematics. Let these students who love mathematics, study mathematics and are good at mathematics express themselves on this stage, motivate themselves, learn mathematics more vividly and develop their mathematical talents. At the same time, it also attracts more students to learn mathematics, love mathematics and develop their intelligence.
