Seven countries entered – Bulgaria, Czechoslovakia, East Germany, Hungary, Poland, Romania and the Soviet Union – with the hosts finishing as the top-ranked nation. [4] The number of participating countries has since risen: 14 countries took part in 1969, 50 in 1989, and 104 in 2009. [5]
The International Mathematical Olympiad (IMO) is a mathematical olympiad for pre-university students, and is the oldest of the International Science Olympiads. [1] It is widely regarded as the most prestigious mathematical competition in the world. The first IMO was held in Romania in 1959. It has since been held annually, except in 1980.

Replace some a i by a variable x in the formulas, and obtain an equation for which a i is a solution. Using Vieta's formulas, show that this implies the existence of a smaller solution, hence a contradiction. Example. Problem #6 at IMO 1988: Let a and b be positive integers such that ab + 1 divides a 2 + b 2. Prove that a 2 + b 2 / ab + 1 ...
In Pakistan, selection for the IMO participants is quite similar to that in other countries. The process starts one and a half year before a particular IMO; and a test (also known as NMTC - National Mathematics Talent Contest) is taken by the high school students which is organized by the Higher Education Commission of Pakistan. The test is ...
Nairi Sedrakyan's son Hayk Sedrakyan is also a professional mathematician and former IMO competitor. [7] [8] Nairi Sedrakyan is known for Sedrakyan's inequality. [9] Nairi Sedrakyan has authored 14 books and around 70 articles in different countries (USA, Switzerland, South Korea, Russia) on the topic of problem solving and Olympiad style ...
