Exploring Absolute Value on the Number Line

This video tutorial introduces the concept of absolute value, explaining it as the distance from zero on a number line. The instructor demonstrates how to find the absolute value of both positive and negative numbers, emphasizing that the absolute value is always a non-negative number. Through various examples, the video illustrates that the absolute value of a number is its magnitude without regard to its sign. The tutorial encourages students to practice finding absolute values with and without a number line, preparing them for more advanced lessons.

What does absolute value represent?
