A mathematical olympiad is a mathematical competition where participants are examined by problem-solving and may win medals depending on their performance. It is usually aimed at pre-university students, and therefore, much of olympiad mathematics consists of elementary mathematics, though solutions may involve the use of calculus or higher-level mathematics. The biggest mathematics olympiad is the International Mathematical Olympiad. Since they measure some mathematical abilities of the students, They identify talented or gifted students in mathematics, who often receive opportunities for scholarships at universities.
