Combinatorics, geometry, and number theory problems

Gary Davis & Adriano Marzullo ©2022

In this document we have collected problems from combinatorics, combinatorial number theory, computational number theory, and geometry that are hopefully understandable, engaging and challenging for High School students and mathematics undergraduates and, with the exception of the unsolved problems, do-able by them.

Our main aim in collecting and presenting these problems is to provide students with a fun collection: problems that stimulate and challenge their mathematical thinking, and are fun to work on.
