Order of Operations Explained

The video tutorial explains the order of operations, often referred to as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. It details the specific steps to evaluate expressions correctly, starting with operations inside parentheses, followed by exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right. An example problem is used to demonstrate these steps, resulting in a final calculated value. The lesson concludes by reinforcing the importance of following the order of operations to accurately evaluate mathematical expressions.
