PEMDAS Explained: Order of Operations with Variables Step by Step

📌 SUMMARY In this video, Ryan breaks down the Order of Operations — also known as PEMDAS — and shows you exactly how to use it to simplify both numerical and algebraic expressions. You'll learn what each letter in PEMDAS stands for, how to handle variables by plugging in values, and how to avoid the most common mistakes students make. By the end, you'll have a reliable, step-by-step system for tackling any expression thrown at you. 0:00 - Introduction & Why Order of Operations Matters 0:40 - Learning Objectives 1:19 - Part 1: Why Does Order Matter?
