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?
Something I haven’t seen mentioned yet is how we remember it as either BEDMAS or PEMDAS, but not PEDMAS or BEMDAS. The order of M and D are tied to whether we use the term brackets or parentheses. BEMDAS sounds very wrong to me
Why? Why would this be important?
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.
