Subtracting Integers with Algebra Tiles

The video tutorial by Mom Cybele explains how to subtract integers using algebra tiles. It introduces the concept of zero pairs, where one green square equals one and one red square equals negative one. The tutorial provides examples of subtracting both positive and negative integers, demonstrating the use of zero pairs to simplify the process. The video concludes with an interactive question for viewers to solve, reinforcing the concepts learned.
