Art of Problem Solving

Art of Problem Solving (AoPS) is an educational resources company founded by Richard Rusczyk in 2003.

The Company


The main goal of AoPS is to create interactive educational opportunities for avid students of mathematics. As time goes on, AoPS is reaching out to students of other problem solving disciplines as well, including informatics, physics, programming, and others.

Tradition of Excellence

The accomplishments of every student are unique, and there is no way to measure that success. However, we try to record and celebrate achievements of AoPS students, faculty, and community members.

Many of the features of the Art of Problem Solving website are made available for free so that every student interested in mathematics can use them.

Additionally, AoPS instructors provide hundreds of hours of teaching and support time for the San Diego Math Circle.

The Art of Problem Solving Foundation is a nonprofit corporation founded by AoPS CEO Richard Rusczyk with largely the same fundamental mission as AoPS itself, but with greater focus on providing educational resources where they are lacking. AoPS donates a portion of its book and class sales to the foundation. A link can be found here.
