Crux Mathematicorum (CRUX) is an internationally respected source of unique and challenging mathematical problems published by the CMS. Designed primarily for the secondary and undergraduate levels, and also containing some pre-secondary material, it has been referred to as “the best problem solving journal in the world”. All the problems and solutions are fully peer-reviewed for clarity, completeness and rigour by academic and professional mathematicians. Crux includes an “Olympiad Corner” which is particularly helpful for students preparing for math competitions.
Since January 2019, Crux Mathematicorum (CRUX) became a free online publication thanks to the support of the Intact Foundation.
