Simplify an Expression with Parentheses and Exponents

The video tutorial explains the order of operations using the PEMDAS rule. It guides viewers through solving a numerical expression by first addressing parentheses, then exponents, followed by multiplication and division, and finally addition and subtraction. The tutorial emphasizes the importance of following the correct order to achieve the correct result, which is demonstrated through a step-by-step breakdown of a sample expression.
