Understanding Distance on a Number Line

The video tutorial focuses on teaching GED students how to calculate the distance between two negative numbers on a number line. It begins by introducing the concept of distance and its challenges with negative numbers. The instructor demonstrates how to visualize this on a number line and then explains the mathematical approach of subtracting numbers to find the distance. The tutorial also covers handling negative subtraction and emphasizes that distance is always positive. The session concludes with a summary and an invitation for students to ask questions.
