Mastering the Order of Operations

In math, we have a special set of rules to tell us which part of a problem to solve first. We call this PEMDAS!

The PEMDAS Steps:

  1. Parentheses ( ) : Solve what's inside the "hug" first.
  2. Exponents : Solve the little "power" numbers.
  3. Multiplication × and Division ÷ : Do these from left to right.
  4. Addition + and Subtraction - : Do these last, from left to right.

Practice Problem

How would you solve this? 2 + 3 × 4

According to PEMDAS, we do multiplication first!

3 × 4 = 12, then 2 + 12 = 14.

If we did it in the wrong order, we would get 20 and that's a math disaster.
