Order of Operations and Basic Arithmetic

In this video, Mr. Jay explains the order of operations, focusing on problems involving fraction bars. He demonstrates how to group the numerator and denominator separately before dividing. Two example problems are solved, each with an alternative method, emphasizing the importance of following the order of operations. The video aims to clarify how fraction bars act as grouping symbols in mathematical expressions.
