In China, mathematics competitions are mainly divided into the national high school mathematics league (the full name of the national middle school mathematics Olympic competition) and the national middle school mathematics league (the full name of the provinces of the national informatics Olympic competition). These two competitions are national-level subject competitions sponsored by the Ministry of Education of China, which contain high gold content. There are also some local math competitions, such as primary and secondary school math competitions in various provinces and cities.
Internationally, the most famous mathematical competition is the International Mathematical Olympiad (IMO). IMO is a global mathematical competition sponsored by the International Mathematical Federation, which is held once a year. It attracts outstanding students from all over the world to participate in and is considered to be the highest level of middle school students' mathematics competition. In addition, there are some other international mathematics competitions, such as American National Mathematics Competition (AMC) and Russian National Mathematics Competition (RUS- MATT).
In a word, math contest is a good way to train students' math ability. It can not only help students improve their problem-solving skills and thinking ability, but also lay a solid foundation for their future study and career.
