If you look at the arguments on math forums, you’ll see that there isn’t just one rule.
It is a convention, and different places teach different conventions.
Namely, some places say that PEDMAS is a very strict order. Other places say that it is PED|MA|S, where D and M are the same level and order is left-to-right, and same with addition vs subtraction.
And others, even in this post, say it’s PEDMAS, which I have heard before.
“Correct” and “incorrect” don’t apply to conventions, it’s simply a matter of if the people talking agree on the convention to use. And there are clearly at least three that highly educated people use and can’t agree on.
Huh it was always pemdas in both highschool and college in new England for me… they were also always parentheses. ‘Brackets’ only reffered to ‘[ ]’ which were reserved for matrices or number sets, eg 2*[2,5,8]+2= [6,12,18]
Order of operations only has one rule: Bedmas (or pemdas if you’re not from north america)

I think canadians call ( ) brackets in math
