Virtual Mathematical Marathon


Dear Friends of mathematics!

We are happy to invite you to join our Virtual Mathematical Marathon which has been developed by an international team of mathematicians, mathematics educators and computer science specialists with the help of the Canadian National Science and Engineering Research Council and its PromoScience program.


The main activity is a competition allowing you to enjoy solving challenging mathematical problems all year around. You can join the competition at any time and at no costs simply creating an individual profile with an individual username and a password. If you prefer the French language, you can switch it at any time by clicking on French at the upper-right corner of the screen.


Every year we offer a Winter Round and Summer Round. Each Round consists in posting 4 (four) new problems on Sunday for 10 Sundays in a row. In total, 40 problems will be posted during one Round. We will announce the dates of each round in the Actuality. All participants will receive an electronic certificate attesting participation. Several prizes will be awarded for merits and perseverance. Detailed list of Winners and Laureats of  Fall2013 you can find here. For more details, see our rules and examples.

New round is now on, please, come and play!

The site is newly created and you are its first users. Please, share with us all experiences by e-mail using our contact us page or simply be sending an e-mail to V.Freiman at
