What math operation order do you use? (lemmy.world)

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?

Its PEMDAS and nothing else

I think the question is whether you interpret that acronym as P E M D A S or P E MD AS (i.e., whether multiplication has higher precedence than division or whether they are the same).

The latter is correct, the former is an unfortunately common misunderstanding.

Until now, it did not occur to me that there are some who believe multiplication and addition come before division and subtraction, respectively. Order of operations clickbait arguments make a bit more "sense" now.

Please excuse my dear aunt sally. I always assumed this was sequential.
