Crux Mathematicorum

Crux Mathematicorum 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.

Submissions:   We're very pleased to welcome submissions of original articles, new problems, and solutions to problems we've published. For more information, see our Contributors & Authors page.
