2013 Sun Life Financial Canadian Open Math Challenge - Nov 6/7
by Prof. Robert Woodrow, COMC 2013 chairman
Each week until the COMC competition is held (Nov 6/7), we will provide a sample problem that is selected to indicate the fun questions can bring. The actual COMC exam has three parts: A, B and C, with four questions each. The easiest are in part A, requiring just a correct answer. The most challenging (and most valuable) are the part C questions which require fully-worked proofs. Part B questions are, naturally, in between. The problems of the week that are posted here tend to aim for the difficulty you'd find in part B, or in an easier Part C problem. They are drawn from a variety of contest sources.
We will post solutions to these problems one week later, but teachers should be aware that determined students may be able to locate solutions elsewhere online before then.
For a more comprehensive set of problems and solutions at each of these levels, please feel welcome to download past official exams and solutions from our archive.
