Introduction to the International Mathematical Olympiad: It has a long history to hold mathematical competitions in middle schools. It is generally believed that it started at 1894 and was organized by the Hungarian mathematics community to commemorate the mathematician Eotvos Roland. Comparing mathematics competition with sports competition, it is the former Soviet Union that is linked with ancient Greece, the birthplace of science. She called the math competition the math Olympics. In the first half of the 20th century, different countries organized all kinds of mathematics competitions at all levels, first in schools, then in regions, and then in the whole country, and gradually formed a pyramid competition system. The further development of national competitions naturally creates the necessary conditions for the formation of the highest international competition. Professor Roman, a Romanian mathematician, put forward an initiative in 1956 and held the first International Mathematical Olympiad (IMO) in Romania in July 1959. Only Bulgaria, Czechoslovakia, Hungary, Poland, Romania and the Soviet Union participated. After that, it will be held once a year (1980 only once), and the number of participating countries and regions will gradually increase. At present, there are more than 80 teams participating in this competition. China participated in the International Mathematical Olympics for the first time in 1985.

After more than 40 years of development, the operation of the International Mathematical Olympiad has gradually become institutionalized and standardized, and a set of established routines has been followed by previous hosts.

1. Objective: To stimulate teenagers' mathematical ability; Stimulate young people's interest in mathematics; Discover the reserve army of scientific and technological talents;

Promote the exchange and development of mathematics education in various countries.

2. Time: held once a year in July.

3. Hosting: Hosting by participating countries in turn, with funds provided by the host country.

4. Object: The contestants are middle school students, each team has 6 people, and 2 mathematicians are sent as the team leader.

5. Test questions: The test questions are provided by the participating countries, then selected by the host country and voted by the examiners' committee, resulting in 6 test questions.

The host country does not provide test questions. After the test questions are determined, they will be written in English, French, German, Russian and other working languages, and the team leader will pay for the translation.

6. Exam: The exam is divided into two days, 4.5 hours a day, and 3 questions. Six members of the same team were killed.

Assign to 6 different examination rooms and answer questions independently. The answer sheet is judged by the national team leader, and then together with the coordinator designated by the organizer.

Negotiation, if there are differences, please refer to the presiding judge for arbitration. 7 points for each question, out of 42 points.

7. Awards: There will be a first prize (gold prize), a second prize (silver prize) and a third prize (bronze prize) in the competition, with a ratio of about1:2: 3; appointment

Half of the contestants won the prize. The award criteria of each session are related to the results of the current exam. IMO is not between teams.

Competition, so there is no team award, but every team attaches great importance to the ranking of the total score of the group, from the situation in recent years.

Look, China, Russian, American, German, Romanian and other countries are stronger.

8. Examiner's Committee: The examiner's Committee is composed of leaders of various countries and the chairman designated by the host country. The chairman usually comes from this country.

Mathematical authority. The main review committee has seven responsibilities:

1), multiple-choice questions;

2), determine the scoring standard;

3) Accurately express the test questions in the working language, and translate and approve the test questions translated into the languages of the participating countries;

4) During the competition, determine how to answer students' questions in writing;

5) Resolve the different opinions on grading between individual team leaders and coordinators;

6) Determine the number and scores of medals.
