Understanding Additive Inverses and Balancing Equations

Mr. Meyers introduces the concept of adding negative numbers, focusing on the additive inverse, which is the opposite of a given value. He explains how adding a positive and its negative counterpart results in zero. Through examples, including a real-life bank account scenario, he demonstrates how to apply this concept. The video concludes with instructions to complete guided notes.
