Understanding Differences on a Number Line

The video tutorial explains how to find the difference between two numbers, 4 and -5, using subtraction. It introduces the concept of using a number line to visualize the distance and direction between numbers. The tutorial demonstrates counting the distance from -5 to 4, resulting in a distance of 9, and explains how to determine the direction as positive by moving right on the number line.
