Founded in 2004 by the Hanoi Mathematical Society, the competition was established to identify young mathematical talent while encouraging higher logical thinking and problem-solving skills in English. The event expanded nationwide in 2013 and opened to international teams in 2018 to strengthen global friendships and mutual understanding between students from Vietnam and abroad.
