Order of Operations Explained

The video tutorial introduces the concept of order of operations, using a story about Denise making cupcakes to illustrate the importance of following steps in the correct sequence. The lesson explains the order of operations using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) and provides examples to demonstrate how to apply these rules to mathematical expressions. Students are encouraged to practice ordering steps and solving expressions to ensure consistent results.
