Pre-Algebra Lesson #24 Divisibility Rules for 2 – 12 | Includes the rules for 7 & 11

http://www.greenemath.com/ In this lesson, we will learn about the divisibility rules for the numbers 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. These rules allow us to quickly determine if a number is divisible by one of these numbers, meaning a division has no remainder. Most of the rules are very simple to learn with the exception of 7 and 11, these are considered a bit tougher to memorize and are covered in a section at the end of the video.
