    It's interesting that you can somewhat tell where you are from based on this, I learned it as BODMAS

    Orders.

    Brackets, Orders (powers and roots), Division, Multiplication, Addition, and Subtraction

    Division, Multiplication, Addition, and Subtraction

    This is fucking so many people over... It should be limited - like Orders - to only Multiplication and Addition.

    Because division is the same operation as multiplication, and subtraction is the same operation as addition, and they have the same "weight" in the order of operations (meaning, you do them left-to-right).

    Another commenter mentioned something similar, how they're interchangeable, but I'm not sure why you say it's fucking people over.

    Because the people who learn "DM" or "MD" then spend hours online arguing that you must do one before the other.

    I learned BODMAS too! It seems BIDMAS is another one (British I think), PEMDAS is the weird American one, BEDMAS is a thing too. You're able to vary the first letter (parenthesis or brackets), second letter (indices/exponent/"order" or "operation"), and the order of multiplication/division (MS or SM) and addition/SUBTRACTION (AD or DA)

    Very interesting indeed.

    I think most former British colonies use BODMAS

    I never ran into PEMDAS while growing up, in Sweden I've always been taught of it as the following order of operations:

    1. P
    2. E & Roots
    3. M & D
    4. A & S

    Technically roots are a form of exponent, just fractional (square root is power of 1/2, for instance). I can see how it could be easier to conceptualize when you break it down like that though. Neat to see the differences compared to the US breakdown :)

    They aren't using the same words so the shorthand (if they have one) is different. I don't think we had a shorthand for it either, we just learned it.

    And we learned them in groups numbered like the Swedes

    Okay then, but, fun story, the BODMAS they're talking about is also just PEMDAS using different words and a different listed order for multiplication/division, with the understanding that it's more properly PE(MD)(AS)

    The order of operations is the important bit and everyone learns it that way. What causes the arguments is when dummies online forget that M+D or A+S can theoretically be done properly in any order and that part is a matter of preference.
