Distance and Absolute Value Concepts

The video tutorial introduces seventh graders to the concept of calculating the distance between two rational numbers. It covers exercises using a number line, explains the formula for distance calculation, and applies it to real-world scenarios. The lesson emphasizes that distance is always positive and assigns homework for further practice.
