### About

Each semester, the Challenge Problem Series offers a new set of mathematical puzzles, designed to stump and to entertain. Everyone, from near and far, is welcome to participate.

UConn studentsâ€”undergraduate and graduateâ€”who submit solutions by the indicated deadline that are deemed worthy are rewarded with chocolate (or, on occasion, something else if there is sensitivity to chocolate).

### Contact

The Challenge Problem Series is written and maintained by Professor Stuart Sidney and Professor Liang Xiao.
