Understanding Operations and Expressions

The video tutorial guides viewers through solving a standardized math test question using the order of operations, also known as PEMDAS. The expression to solve is '2 subtract 3 multiplied by 4 subtract 5'. The tutorial explains how to simplify expressions within parentheses, and then multiply the results. The final answer is calculated to be 1, demonstrating the importance of following the correct order of operations in math problems.
