A panel in the Mathematics Department publishes a challenging problem once a week and invites college & pre-college students, faculty, and staff to submit solutions. The objective of this is to stimulate and cultivate interest in good mathematics, especially among younger students. Solutions are due within two weeks from the date of publication and should be sent by campus or U.S. Postal mail to:

Problem of the Week

Department of Mathematics, Purdue University

150 N. University Street, West Lafayette, IN 47907-2067

Solutions may also be emailed as a pdf attachment to Shu-fang Chang or faxed to 765-496-3177.

Questions and concerns about Problem of the Week can be directed to Shu-fang Chang.

Every Purdue student who submits three or more correct solutions will receive a Certificate of Merit. Each semester, a prize fund of $300.00 will be distributed among the Purdue undergraduates who have contributed at least six correct solutions for that semester series.

## About the founder of Problem of the Week

Michael Golomb, who passed away on April 9, 2008 at the age of 98, began the Problem of the Week program and ran it for many years. A few years ago, health problems forced him to stop administering the program, but he continued to provide the problems. And even now many of the problems appearing in Problem of the Week were provided by Michael Golomb. He created many of the problems himself, and collected (and often modified) the others from various sources.
