Order of Operations

The video tutorial explains the order of operations, commonly known as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. It details the steps to evaluate mathematical expressions using this order. The tutorial provides an example expression and demonstrates how to solve it step-by-step, ensuring the correct application of PEMDAS. The lesson concludes with a summary of the key points covered.
