Understanding Absolute Value Expressions

The video tutorial explains how to simplify an absolute value expression. It begins by defining absolute value as the distance from zero, which is always positive. The tutorial then demonstrates simplifying expressions within absolute values, calculating the absolute values of numbers, and performing final simplification steps to arrive at the solution. The example used involves simplifying the expression |5 - 8|, which results in the absolute value of -3, equaling 3.

What is the absolute value of a number?

• The number itself
