Modular Arithmetic: User's Manual

Modular arithmetic visually! How to compute modulo n, efficiently and with intuition. We rely heavily on visual intuition. This video is appropriate for anyone interested in modular arithmetic! It could be used in high school, for an introduction to proof course, for undergraduate mathematics or computer science majors, or for the mathematically inclined, especially those interested in cryptography or number theory. This is part of a series on modular arithmetic with visualization:    • Modular Arithmetic Visually   For associated materials: https://proofofconcept.katestange.net...
