International Mathematical Olympiad «Formula of Unity» /​ «The Third Millennium» continues two earlier independent Olympiads: «Formula of Unity» that took place in 2012/​13 and «The Third Millennium» that has been conducted since 2001. The united Olympiad was first held in 2013/​14 academic year. In the year 2014/​15 it gathered more than 6,000 students from 15 countries.

Nowadays the Olympiad is organized by ITMO University, Northern (Arctic) Federal University named after M.V. Lomonosov, Southwest State University and Euler Foundation.

We invite schoolchildren of 5 – 11 grades from schools of Russia and schoolchildren of 11 – 17 years old from all over the world. The Olympiad is held in two rounds, the first one is extramural (October-November), the second one is intramural (February).

Olympiad problems are translated into several languages such as English, French, Persian, Russian, Spanish, Uzbek and some others. Contestants are allowed to write their solutions in those languages.

Participation is free of charge. All school students can take part in the first round and the winners of the first round are invited to the second round. Winners of the previous Olympiad (with diplomas of any degree) are also invited directly to the second round. Participants with the best results in the second round will be awarded with diplomas and invited (with reduced fee) to the international mathematical camp «Formulo de Integreco».
