Math Corner #1 Mystery Cache

My friend Chris is finishing his Masters degree in Math and teaches Pre-Calculus at UNLV.  He is a fellow hiker & when I brought up the idea of making a series of math-based puzzle caches, he happily agreed to help create this series.  Some will be fairly easy & some will be quite difficult.  No hiking needed for this one! Good luck!
