Kenyon College Mathematics Department Problem of the Week Page

• Problems will be posted bi-weekly.
• Among all complete and correct submissions for a given problem, one winner will be selected randomly. The winner receives a $15 gift certificate for the Kenyon bookstore.
• Only current Kenyon students are eligible for the prize.
• If there is no correct solution received for a given problem, the prize will roll over to the next problem. The money will accumulate until a correct and complete solution is received for the current problem.
• Submit your solution as soon as you find one but before the deadline.
• We will keep a record of all correct submissions and the best problem solver overall for each semester/year (the person who submitted the highest number of correct solutions in a year/semester, regardless of how many times the person was the winner). The best problem solver might get a surprise award!
