The Acton-Boxborough Math Competition (ABMC) is a competition designed for middle school students across MA.

We accept teams of 2-4 students as well as individual competitors.


ABMC is uniquely designed such that every participant can solve a sizable portion of the problems. The difficulty ranges from that of simple arithmetic, algebraic, and geometric problems to that of the AMC. All participants will have problems they can solve and problems that will challenge their mathematical problem-solving skills.

Additionally, ABMC provides online contests that are free. Since we reach hundreds of students annually through these contests, we would appreciate donations of any amount to helpus cover the cost of awards, web hosting, and other operations. If interested, feel free to donate to the ABMC PayPal at abmathcompetition@gmail.com or email us for more information.

If you have any questions or would like to sponsor us, please do not hesitate to contact us!
