## Problem of the Month

These problems are designed to promote problem solving and encourage students to delve deeper into mathematics. The problems of the month come from a variety of undergraduate subjects and can be used as a prelude to solving the more sophisticated problems that are available in MAA journals such as *The College Mathematics Journal* and *The American Mathematical Monthly* as well as those appearing in the Putnam Competition. Solutions appear the following month.
