 TOPICS This page:   proof  About Levels of Difficulty About the PoW Library Discrete Math: Proof Proof plays a very important role in discrete mathematics. Sometimes the goal of a discrete mathematics proof is to show that a solution exists. At other times the goal is to show that all possible solutions to a particular problem have been found, or that the optimal solution has been discovered. Several of the problems listed below require students to create and prove a formula for a particular sum. For background information elsewhere on our site, explore the High School Discrete Math area of the Ask Dr. Math archives. To find relevant sites on the Web, browse and search Discrete Mathematics in our Internet Mathematics Library. Access to these problems requires a Membership.
