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?
It’s not important, just an observation of spoken language. Similar to the order of adjectives or how there’s usually a “correct” sounding way to list two names.
If anything, it might explain why people are tied to a particular order of multiplication and division

FWIW they all sound equally ok to me. I never learned any of these acronyms, tho I’ve come across them on occasion, and if someone had presented any of the 4 as THE acronym for this I’d have believed them.
I think because I read about this riddle in the past, I might have built up some associations myself. So maybe there’s actually nothing there 😄
