Mastering Integer Addition with Color Counters

This video tutorial explains how to add integers using two-color counters. It begins with a review of integer representation using yellow and red counters for positive and negative values, respectively. The tutorial then provides three examples: adding negative eight and positive five, adding positive seven and negative three, and adding positive six and negative six. Each example demonstrates how counters can be used to simplify the addition process, highlighting the concept of zero pairs and the result of adding opposites.
