Hellenic Mathematical Society
The Hellenic Mathematical Society (EME), founded in 1918, is the primary organizer of mathematical competitions in Greece. It manages the full pipeline from the introductory Pythagoras competition through to Greece's IMO team selection. EME operates through regional branches across Greece and works closely with schools to promote mathematics at all levels.
Official WebsiteCompetitions Organized
Pythagoras
The Hellenic Mathematical Society's math skills competition for students in grades 2-9 (elementary and gymnasium). Features 20 multiple-choice questions testing mathematical reasoning, not rote knowledge. Held annually on a single Saturday in March.
Thales
The first phase of Greece's secondary school math competition pipeline (grades 7-12). Open to all students, with top performers qualifying for Euclid. Proof-based format requiring full written solutions.
Euclid
The second phase of Greece's EME competition pipeline. By invitation only for top Thales performers. More challenging proof-based problems requiring sophisticated mathematical reasoning.
Archimedes
The third and final qualifying stage of Greece's EME pipeline before the National Olympiad. Olympiad-level proof problems for top performers from Euclid.
Greek Mathematical Olympiad
Greece's national mathematical olympiad, the final selection stage for the IMO team. By invitation only for top Archimedes performers. IMO-style format with 6 problems over 2 days.
