Understanding Absolute Values of Rational Numbers

This video tutorial covers the concept of absolute values, focusing on their definition as the distance from zero, which is always positive. It explains how to use number lines to find absolute values of rational numbers, providing examples with both positive and negative numbers. The video also discusses the concept of opposites on a number line and their equal absolute values. The tutorial concludes with a brief overview of the next lesson on comparing and ordering rational numbers.
