Order of Operations Evaluation

This lesson focuses on the order of operations, specifically using the fraction bar as a grouping symbol. The instructor explains how to evaluate expressions in the numerator and denominator separately, following the order of operations. The lesson includes a detailed walkthrough of solving an example problem, emphasizing the importance of evaluating the numerator first, followed by the denominator, to arrive at the correct final answer.
