Understanding Subtraction Concepts

This video covers module two, lesson five, focusing on understanding the subtraction of integers and rational numbers. It introduces the integer game as a tool to explore subtraction rules, emphasizing the concept of adding the additive inverse. The lesson includes examples using number lines and exercises to reinforce understanding. Key concepts include the rule that subtracting a number is equivalent to adding its opposite.
