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.

    Because you don't want people to know when to do Division and Subtraction? 😂

    Because division is the same operation as multiplication

    No it isn't, but they are both binary operators.

    they have the same “weight” in the order of operations (meaning, you do them left-to-right)

    And where are they going to do Division and Subtraction in the left to right if you've left them out? 🙄

    Because division is multiplication, and subtraction is addition.

    No it isn’t, but they are both binary operators.

    2/2 is the same as 2*½

    2-2 is the same as 2+(-2)

    And where are they going to do Division and Subtraction in the left to right if you’ve left them out? 🙄

    Well, as I already said multiple times: Division = Multiplication and Subtraction = Addition, therefore they would be doing them together, left to right. As in: 9-3+2 would not confuse anyone who learned "Addition → Subtraction", as it does right now.

    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
