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?
Yeah, differentiating between multiplications vs. divisions and additions vs. subtractions doesn’t make sense, because they’re the same thing respectively, just written differently.
When you divide by 3, you can also multiply by ⅓.
When you subtract 7, you can also add -7.There is one quirk to be aware of, though. When people notate a division with a long horizontal line, that implies parentheses around both of the expressions, top and bottom.
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
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.
Please excuse my dear aunt sally. I always assumed this was sequential.
Exponents are typically highest exponent first.
10^10^10 implies 10^(10^10) not (10^10)^10 which is astronomically different.PEMDAS
Parentheses, exponents, multiplication, division, addition, and subtraction.
Never met multiple exponents in a row at the same size and level without brackets/parenthesis, always saw them as a^b^c, or a^(b^(c)) , so I didn’t even think about that case.
BEDMAS cuz all y’all “parentheses” people are way too hoity toity and they’re called Brackets, y’all
