Problem of the Month

The NAMC problem of the month is a collection of problem sets designed to encourage interaction between various math circles around the world. Each month our circle and others across the country will get a set of challenging problems. Individual problem solving is fine but everyone is encouraged to collaborate with others to create the most elegant solutions. We would like to see solutions submitted by math circles. solutions can include photographs, image files, pdf files.

Solutions will be publicly recognized by the world’s best Math Circles and other math circle organizations. Comments and discussions related to the problems and solutions are encouraged.

We are very interested in problems written by students. Writing problems is one of the best ways to improve problem solving skills. In addition, creating good questions is one of the most important skills that a mathematician can have, and it is essentially never taught. The authors of those problems that are accepted for distribution will receive special recognition. People or math circles can submit as many problems as they wish per month. Problems that are not used one month may be used in the future. Submissions can be labeled with the names and ages and math circle/school affiliations, of the people who create the problems.

  • Problems should not be copied directly from another source, but may be inspired by existing problems.<\li>
  • It is a good exercise to create questions after math circle sessions. These might inspire problems for Problem of the Month.
  • Problems should be submitted to
  • Please let the NAMC know what author information you would like published with the problem. It could range from nothing, to a first name and state, AOPS ID, all the way to a short bio or description.

Solutions will not be published until the problem has been listed for one month. After that solutions can be added at any time. Indeed we hope that interesting exchanges will take place between members of distinct math circles around the world.

Problem of the Month was initiated by Dr. Dana Paquin, the former director of the Stanford Math Circle, and refined through discussions with Dave Auckly, David Cordeiro, Joshua Zucker, Brandy Wiegers, Maria Droujkkova, Dimitar Grantcharov, Ming Jack Po, Shri Ganeshram, Mary O'Keeffe, Julia Brodsky, Ted Alper, Matthias Kawski, and Tony He. Thus the very creation of the program involved collaboration between many different math circles.
