Navigating Parentheses and Brackets in PEMDAS

In this video, Mr. J explains how to solve order of operations problems involving nested parentheses and brackets. He demonstrates the process using two example problems, emphasizing the importance of following the PEMDAS rule: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The video breaks down each problem step-by-step, showing how to handle multiple sets of parentheses and brackets. By the end, viewers should feel more confident in tackling these types of math problems.
