2021 Math Contest: Math Prize Problem #1

Each month the Mathematics Department offers a math prize problem – a mathematical brain teaser – with a first prize of $25, a second prize of $15, and, of course, bragging rights. These problems do not require advanced knowledge of mathematics, just a curious mind and a willingness to slug it out with the problem.

Arrange the ten integers 1, 2, 3, …, 10 in a circle so that the sum of any three consecutively positioned integers is divisible by 3, or show that it is impossible.


Submit a solution to this problem to Prof. Ken Ching (kching@mmm.edu, CH 614) by November 10th. The first correct submission will win a $25 cash prize. All other correct submissions will receive recognition and bragging rights, and one of these submissions will be randomly selected for a $15 second prize. All are welcome to participate, but cash prizes are for MMC students only. Solution will be posted online and outside CH 603.

Happy Solving!


Dr. Ken Ching
Associate Professor of Mathematics
