I have seen several people saying the order operation is
- Brackets/Parenthesis
- Orders (roots and powers)
- Divisions
- Multiplications
- Subtractions
- Additions
But I was taught it as
- Brackets/Parenthesis
- Roots and powers, left to right (independently of the exact operation)
- Divisions and multiplications, left to right (independently of the exact operation)
- Subtractions and additions, left to right (independently of the exact operation)
So, what order were you taught and/or use today?


If there is confusion, you wrote it wrong. Don’t inline it, use a proper equation in whatever software you’re using. If you need to inline it, go heavy on parentheses.
