Mastering Order of Operations With Four Examples

Math with Mr. J

This instructional math video provides a comprehensive guide to solving complex arithmetic expressions using the Order of Operations, commonly remembered by the acronym PEMDAS. The narrator, Mr. J, methodically breaks down the rules: Parentheses, Exponents, Multiplication/Division (left to right), and Addition/Subtraction (left to right). He emphasizes the importance of following these steps to ensure accurate results in problems involving multiple operations. The video features four distinct examples that increase in complexity. It covers standard parentheses, exponents (squared and cubed numbers), implicit multiplication (a number directly outside parentheses), and nested operations where multiple steps must occur inside a grouping symbol. Special attention is given to common misconceptions, such as the order of addition versus subtraction and the true meaning of exponents. For educators, this resource serves as an excellent direct instruction tool or review for pre-algebra students. The step-by-step visual demonstration on a digital chalkboard helps students model their own work organization. It is particularly useful for clarifying the strict left-to-right rule for multiplication/division and addition/subtraction, a concept that often confuses students.
