In commmon core in the USA did they change the Order of operations recently in the past 5 years?

Brackets is common parlance in Commonwealth countries for what people in Europe the United States call parentheses.

It is the same order of operations. (Division and multiplication are inverse actions of the same process).

I was never taught a mnemonic phrase for order of operations. They just hammered that shit in harder and harder.

We did get FOIL for the quadratic.

What zenvelo said. MD and DM are interchangeable because they’re the same operation, as are AS / SA, and P = B, so

PEMDAS =
BEDMAS =
BEMDAS =
BEMDSA =
BEDMSA =
PEDMAS =
PEMDSA =
PEDMSA

The MD and SA could just be M and A.

The order of operations makes sense if you think of it as doing the most powerful operations first. Exponentiation represents many multiplications so it goes first. Multiplication and division represent multiple additions/subtractions so they come next. The purpose of parentheses and brackets is to override the order of operations. It is highly unlikely that these rules will change anytime soon.

These are universal rules and not just in USA. Don’t think they’re gonna change in my lifetime atleast!!

I used to teach PEMA, rather than splitting up M/D, A/S (PEMDAS) for that every reason. It would be logical to think that multiplication is “more important” than division, etc.
