Subtracting real numbers a positive from a positive, 5 - 3

The video tutorial explains how to use the additive inverse to simplify subtraction problems. It introduces the concept of additive inverse, which states that a number plus its opposite equals zero. The tutorial demonstrates how to rewrite subtraction as addition using the additive inverse and solve problems using a number line. This approach helps in understanding and solving subtraction problems more easily.

What does the number line represent in terms of positive and negative distances?

Provide an example of a subtraction problem and demonstrate how to solve it using the additive inverse.
