Mastering Order of Operations with PEMDAS

This video tutorial covers the order of operations, commonly known as PEMDAS. It explains each component: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). The tutorial includes examples of simplifying expressions and evaluating functions using PEMDAS. It also highlights common mistakes, such as multiplying before dividing when division comes first. The video aims to help viewers correctly apply the order of operations in mathematical expressions.
