To put it simply, mathematics competition refers to all competitions about mathematics, which are generally held in China; The Olympic Games is usually synonymous with international competitions. Therefore, Mathematical Olympics generally refers to international mathematical competitions, which are generally held abroad. Nowadays, the Olympic Games and its spirit have been widely known, so some domestic events will also use the "Olympic Games" and its spiritual connotation to advocate and name events. At present, the main mathematics competitions in China and their organizers are: the National Primary School Mathematics Olympics (chinese mathematical society Popularization Committee), the National Primary School Mathematics Invitational Tournament (Popularization Department of China Association for Science and Technology, China Optimization Method and Economic Mathematics Research Association, China Laboratory, Mathematics World magazine and Zhongqing Online website), the summer camp of "I love mathematics" for primary schools-the National Primary School Mathematics Olympics Finals (chinese mathematical society Popularization Committee). National "Huajin Cup" Junior Mathematics Invitational Tournament-Primary schools (China Children's Press and Publication General Agency, China Optimization Law and Economic Mathematics Research Association, CCTV Youth Center, China Laboratory, China International Science Exchange Foundation, etc.) The National Junior High School Mathematics League (Popularization Committee of Chinese Mathematics Society) and other regions have cancelled the competition "National Junior High School Mathematics Competition" (Middle School Mathematics Teaching Professional Committee of China Education Society).
