Navigating Order of Operations with Exponents

In this video, Mr. J explains how to solve order of operations problems involving exponents. He introduces the PEMDAS rule, which prioritizes parentheses, exponents, multiplication, division, addition, and subtraction. The video includes two example problems. The first problem involves solving an expression with parentheses and exponents, while the second problem includes exponents and division. Mr. J walks through each step, emphasizing the importance of following the correct order to arrive at the correct solution.
