Problem of Week!

On this page you will find a new, challenging, unusual math problem, updated every week! The answers will not be given until the next week, but if you're really dying to find out if you got it right, you can email me with your answer and I'll let you know how close you were. If you do wait until the answers are posted, you must go to the POTW archives to see the answer.  It will be with its problem.

Problems from past weeks are kept in our POTW Archives.

If you have a problem you would like to have put on this page, send it to me! All contributions welcome.
