Subtracting Integers Using the Opposite Method

The video tutorial teaches how to subtract integers using tiles. It begins with an introduction to the concept of adding the opposite when subtracting integers. The instructor provides three examples: positive 3 minus positive 2, negative 8 minus negative 2, and positive 5 minus negative 1. Each example is demonstrated using yellow and red tiles to represent positive and negative integers, respectively. The video concludes with practice questions and encourages viewers to subscribe for more tutorials.
