Challenge of the Week Competition

December 14, 2010

This concludes the Challenge of the Week for Fall 2010.

Challenge #10 has been won by Renee Fietsam, Phillip Sterling, and Lester Wang!


We are going paperless!  We will no longer distribute paper versions of the challenge in the classrooms, so tell your friends that they can access the challenge on this web site.  The Mathematics department web site has a link to this site so it is easy to find.



This page contains links to the Challenges of the Week (and the EIU Problem-Solving Competitions) from 1988 until the present date.

If you would like to see the challenges, click on problems, below. The link to the solutions will show you both the challenges and their solutions.

Note: You will need to have Acrobat Reader (freely available) in order to read these files.
