The 'Kangaroo' mathematics competition, traditionally associated with school students, has been expanding its reach to include adults for several years now, particularly through an 'Expert' age group aimed at math and logic problem enthusiasts. This initiative allows individuals outside of the school system to test their skills and engage with math in a competitive environment. Participation is straightforward; interested individuals can register on the competition's official website and solve problems online during the designated competition window from March 19 to May 31.
