Order of Operations (PEMDAS)

Parentheses, Exponents, Multiply/Divide, Add/Subtract.

Formula

P→E→(M÷D)→(A÷S)P \to E \to (M \div D) \to (A \div S)

Variables

Example

2 + 3×4 = 14, not 20

Did You Know?

PEMDAS is a convention, not a law of nature — different countries teach BODMAS or BIDMAS, but they all mean the same order.
