Math Drill is free to use for personal, family and classroom practice. You do not need an account. By using the site you agree to these terms.

Provided as is

We work to keep the problems correct and the game running, but Math Drill is provided "as is", without warranties of any kind. It is a practice tool and does not replace a teacher or a school curriculum. Grade levels follow Japan's elementary school math curriculum and may not match your school exactly.
