The 66th International Mathematical Olympiad (IMO 2025) took place on the Sunshine Coast, Queensland, Australia, with the participation of 639 contestants from 113 countries and territories. A total of 321 medals were awarded, including 72 gold, 104 silver, and 145 bronze medals.
This year’s International Mathematical Olympiad (IMO) consisted of six problems, including two in number theory, two in combinatorics, one in geometry, and one in algebra. Notably, Math Exercise 2 of the only geometry problem in the competition was proposed by Vietnam. The problem was authored by Mr. Tran Quang Hung, a mathematics teacher at the High School for Gifted Students of Science in Hanoi.
It is the fourth time Vietnam has contributed a problem to the official IMO examination. Previous Vietnamese-authored problems appeared in 1977 by Phan Duc Chinh, in 1982 by Van Nhu Cuong, and in 1987 by Nguyen Minh Duc.
