01 — Olympiad

What is the MT Classes Math Olympiad?

It is a math competition for children aged 9–14 who enjoy thinking, looking for ideas and explaining their solutions.

The goal is not just to guess the answer. Participants write down their reasoning, try different approaches and discover mathematics as a space for ideas, not just a set of formulas.

The Olympiad takes place in person at partner venues in different countries.
