Order of Operations and Exponents

This video tutorial from Moomoomath explains how to use the order of operations, known as PEMDAS, to correctly evaluate mathematical expressions. The video provides three examples to illustrate the importance of following the correct sequence: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). Each example demonstrates common mistakes and the correct method to solve expressions. The video concludes with a reminder to subscribe for daily math and science content.
