Here is the qualifying (remote) round of the competition. You can solve problems until 23:59:59 UTC, 10 November 2021 inclusively.
Please remember that your solution of every problem should include not only the right answer but the full reasoning as well.
We will be happy if your friends who like mathematics also participate. However, every assignment should be done individually; otherwise, your submission will not be considered. The winners of Olympiad 2019/20 (those with Diplomas I‑III) can participate directly in the final round.
How to submit solutions
The solutions should be written in English, Esperanto, French, Georgian, German, Kazakh, Persian, Romanian, Russian, Spanish, Thai, Turkish, Ukrainian, Hebrew or Uzbek. Use of other languages should be agreed with the organizers in advance.
The solutions should be submitted to the Jury by November 10 in our information system:
You can upload both text files (in TXT, DOC, DOCX or PDF formats) and scans of paper works (in JPG and PNG formats):
- each solution must be in it’s own file,
- the total number of files should not exceed 10,
- the files should not contain the surname, name and other personal data of the participant,
- you do not need to repeat the text of the problems in your paper.
