Understanding Absolute Values

This video tutorial explains the concept of absolute values, which represent a number's distance from zero on a number line, always as a positive value. It covers how to calculate the absolute value of both positive and negative numbers, and explores the concept of negative absolute values, where the result is the opposite of the absolute value. The tutorial uses examples to illustrate these concepts, emphasizing that the absolute value is always positive unless specified otherwise.
