Delving Deeper
Delving Deeper: Divisibility Tests

Allen Olsen 

August 2006, Volume 100, Issue 1, Page 46

This issue focuses on divisibility tests. The author discusses a general algorithm for discovering divisibility tests for almost all integers, and applications of these divisibility tests in the classroom. The aim of Delving Deeper is for teachers to pose and solve novel math problems, expand on mathematical connections, or offer new insights into familiar math concepts. Delving Deeper focuses on mathematics content appealing to secondary school teachers. It provides a forum that allows classroom teachers to share their mathematics from their work with students, their classroom investigations and products, and their other experiences. Delving Deeper is a regular department of Mathematics Teacher.
