Teaching order of operations, step by step

The order of operations is: parentheses, then exponents, then multiplication and division from left to right, then addition and subtraction from left to right. US classrooms call it PEMDAS. The UK and other countries use BODMAS or BIDMAS for the same rules.

The left-to-right rule causes the most errors. PEMDAS lists multiplication before division, but they have equal priority, so 24 ÷ 4 × 2 is 12, not 3. These sheets include problems that test exactly that.

Questions

Is PEMDAS the same as BODMAS?

Yes. Both mean brackets or parentheses, then powers, then multiplication and division, then addition and subtraction.

Do multiplication and division have the same priority?

Yes. Do whichever comes first from left to right. The same goes for addition and subtraction.
