He won a gold medal when he just turned thirteen in IMObecoming the youngest person at that time [69] to receive a gold medal a feat matched in by Zhuo Qun Song of Canada.

The examination consists of six problems.

The team leaders arrive at the IMO a few days in advance of the contestants and form the IMO Jury which is responsible for all the formal decisions relating to the contest, starting with selecting the six problems from the shortlist.

International Mathematical Olympiad

In countries of the former Soviet Union and other eastern European countries, a team has in the past been chosen several years beforehand, and they are given special training specifically for shoortlist event. What is the maximum possible number of weak quartets?


Calculus, though allowed in solutions, is never required, as there is a principle that anyone with a basic understanding of mathematics should understand the problems, even if the solutions require a great deal more knowledge. China at International Mathematical Olympiad”. The current ten countries ijo the best all-time results are as follows: It has since been held annually, except in Views Read Edit View history.

The first IMO was held in Romania in Must be Terence Tao”. Express as the smallest possible number of positive or negative cubes.

However, they are usually disguised so as to make the solutions difficult. The problems chosen are from various areas of secondary school mathematics, broadly classifiable as geometrynumber theoryalgebraand combinatorics.

US at International Mathematical Olympiad”. The line KM meets the incircle again at N.

The shirtlist is held over two consecutive days; each day the contestants have four-and-a-half hours to solve three problems. Cumulative Results by Country”. The circles S and S’ meet at A and B. Special prizes may be awarded for solutions of outstanding elegance or involving good generalisations of a problem.

Each problem is worth seven points, so the maximum total score is 42 points. By using this site, you agree to the Terms of Use and Privacy Policy.


Subject to these conditions, an individual may participate any number of times in the IMO. Teams are not officially recognized—all scores are given only imk individual contestants, but team scoring is unofficially compared more than individual scores.

As the leaders know the problems in advance of the contestants, they are kept strictly separated and observed.

A graph has points. A, B are distinct variable points on the circle S not at P or Q. Note that both Elkies and Tao could have participated in the IMO multiple times following their success, but entered university and therefore became ineligible. Soviet Union [n 2]. A tromino is an L shape formed from three squares. The International Mathematical Olympiad is one of the most prestigious mathematical competitions in the world. B seeks to identify shortllst. They require no knowledge of higher mathematics such as calculus and analysisand solutions are often short and elementary.
