Simplifying Expressions and Operations

The video tutorial explains how to simplify a mathematical expression by following the order of operations. It emphasizes the importance of treating absolute values as grouping symbols and demonstrates the process of simplifying both the numerator and the denominator separately before combining them. The tutorial concludes by simplifying the fraction to its simplest form.

What is the first step in simplifying an expression according to the order of operations?
