The 2016 Canadian Open Mathematics Challenge — Nov 3/4

The Canadian Open Mathematics Challenge (COMC) is Canada's premier national mathematics competition that is open to any student with an interest in and grasp of high school math. The purpose of the COMC is to encourage students to explore, discover, and learn more about mathematics and problem solving. The competition serves to provide teachers with a unique student enrichment activity during the fall term.

Approximately the top 50 students from the COMC will be invited to write the Canadian Mathematical Olympiad (CMO). Students who excel in the CMO will have the opportunity to be selected as part of Math Team Canada -- a small team of students who travel to compete in the International Mathematical Olympiad (IMO). Depending on grade level and performance, students participating in the COMC can also have opportunities to garner awards, to win prizes, to be considered for scholarships, and to get invited to camps.

Returning for 2016: Teacher Appreciation Prizes


The 2016 COMC will be held on Thursday, November 3rd in Canada and the Americas (anywhere in North/South American time zones), and on Friday, November 4th elsewhere in the world.


Teachers can register their schools for the COMC by clicking the link below. Registration costs CAD$13.00 per student in Canada and USD$17 per student for international participants.

Problem of the Week!

During the weeks prior to the COMC competition, the CMS is happy to present our Problem of the Week (POTW). Please visit our POTW page for past problems and solutions. Here is the latest problem:

Let $p$ be the number of functions defined on the set $\{ 1, 2, 3, ..., m \}$, $m \in \mathbb{N}^{*}$, with values in the set $\{1, 2, ..., 35, 36\}$ and $q$ be the number of functions defined on the set $\{ 1, 2, 3, ..., n \}$, $n \in \mathbb{N}^{*}$, with values in the set $\{1, 2, 3, 4, 5\}$. Find the least possible value for the expression $|p-q|$.

Stay informed!
