Puzzles of the Week Contest

Welcome to the Math Puzzles of the Week Contest! Everyone is encouraged to have fun and try each problem.

Each week, a new problem will be emailed to all math and CS students, plus posted in the deparment hallway and Math classrooms. Solutions are due on Mondays at 5pm. The Honor Roll list of successful students will be posted in the Math Dept every Tuesday morning. At the end of the term, the students who solve the most problems will win prizes!
