Mastering the Order of Operations with PEMDAS

In this video, Mr. Jay explains the order of operations, a set of rules for solving mathematical expressions consistently. He introduces the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). Through four examples, Mr. Jay demonstrates how to apply these rules to solve expressions accurately. The video emphasizes the importance of following the order of operations to ensure everyone arrives at the same solution.

What is the first step in the order of operations?

• Multiplication

• Parentheses

• Exponents

• Addition
