Understanding Segment Lengths

The video tutorial explains how to calculate the length of line segments on a number line. It begins with segment BD, showing different methods to find the distance between points B and D. The tutorial then covers calculating the distance between points 1 and 4, and finally, it demonstrates finding the length of segment AD. The video emphasizes understanding the concept of distance on a number line and provides step-by-step examples for clarity.

What is the length of segment BD if point B is at -2 and point D is at 5?
