Simplifying an expression by adding and subtracting

The video tutorial explains how to use the order of operations to solve a math problem. It begins with an introduction to the concept, followed by the application of the distributive property to remove parentheses. The tutorial then covers the concept of double negatives, comparing it to English grammar, and explains how subtracting a negative number results in addition. Finally, the video demonstrates the step-by-step simplification of the expression, working from left to right, to reach the final solution.
