### WHAT IS IMOCSEA?

The **International ****Mathematics ****Olympiad Competition of Southeast Asia**, IMOCSEA for brevity, is an international competition in **Mathematics** for Primary Levels and Secondary Levels. It aims to promote excellence and proficiency in Mathematics (Arithmetic, *Number Theory, Number Theory, Algebra, Geometry, Logical Analysis, and Combinatorics*) through friendly global competitions and to promote **Southeast Asia’s tourism**, with **Philippines** as the first destination, then Indonesia, Singapore, Malaysia, Myanmar, Brunei, Cambodia, Laos, Thailand, and Vietnam to other country partners worldwide.

### THE ORGANISATION BEHIND IMOCSEA

IMOCSEA is organized by GLOBAL LEAGUE OF WINNERS, INC. or **GLOW**. It is a duly registered nonstock, nonprofit organization operating in Cebu City, Philippines, with a number of Ambassadors coordinating with its promotion and administration. It is also promoted worldwide by partner organizations in different countries.
