I think your sentence was cut off. The correct rule is:

- Do operations in this order: Parentheses → Exponents → Multiplication and Division → Addition and Subtraction.
- Important: Multiplication and division are the same priority and are done left to right. Addition and subtraction are the same priority and are done left to right.

So you should perform multiplication and division (left to right) before doing addition and subtraction (left to right). Examples:
- 8 ÷ 4 × 2 = (8 ÷ 4) × 2 = 4
- 6 − 3 + 2 = (6 − 3) + 2 = 5
- 3 + 4 × 2 = 3 + (4 × 2) = 11

A common mnemonic is PEMDAS, but remember the MD and AS pairs are left-to-right, not that M always comes before D or A always before S.
