Order of Operations and Simplification

The video tutorial explains how to simplify expressions using the order of operations, focusing on problems involving a fraction bar. The instructor suggests treating the top and bottom of the fraction as separate problems. The video provides a detailed walkthrough of solving each part, emphasizing the importance of following the order of operations: parentheses, exponents, multiplication, and addition. The final solution is presented, along with tips to avoid common mistakes, such as misplacing numbers in the fraction.

What is the first step in simplifying expressions using order of operations?
