How to Use PEMDAS to Solve Math Problems

Math with Mr. J

This educational video provides a clear, step-by-step introduction to the Order of Operations in mathematics, specifically targeted at 5th-grade students. Using the acronym PEMDAS (Parentheses, Exponents, Multiply/Divide, Add/Subtract), the instructor guides viewers through solving four distinct math problems that increase in complexity. The video utilizes a digital chalkboard format to visually demonstrate how to simplify expressions line-by-line, emphasizing the importance of following specific rules to arrive at the correct answer. Key themes include the hierarchy of mathematical operations, the role of parentheses, and the specific rules for handling operations of equal priority. The instructor explicitly addresses common sticking points, such as implied multiplication when a number sits adjacent to a parenthesis and the "left-to-right" rule for multiplication/division and addition/subtraction. The visual layout, with a permanent reference chart on the left, reinforces the systematic approach required for these problems. For educators, this video serves as an excellent instructional tool for introducing or reviewing the Order of Operations. It is particularly useful for clarifying the misconception that multiplication always comes before division or addition before subtraction, as the instructor deliberately includes examples that require applying the left-to-right rule. The clear visual modeling of rewriting the equation after each step provides a strong template for students to organize their own written work.
