Adding Integers Using Number Lines

Mrs. C explains how to add integers using number lines and provides rules for adding integers without them. The video covers examples of adding positive, negative, and mixed sign integers, as well as adding multiple integers and opposites. The lesson concludes with practice examples and a summary of the rules.
