    Brackets, Exponents, Division/Multiplication, Addition/Subtraction -- ALWAYS in that order.

    Thus:
    48/2(9+3) -- the brackets first, 9+3 = 12, which gives us
    48/2*12 -- then division/multiplication... this must be done left to right, therefore you must do 48/2 BEFORE multiplying by 12, and not 2 x 12 first. Otherwise, it would be 48/(2*12) -- anyway, the answer is 24*12 = 288.

    Also... how the hell do things like this become memes?

    Tricky, tricky, Zexis. It's 288. You always go left to right.

    Unless you use... implied multiplication.

    2/5x ... normally you'd read that as 2/(5x)... or would you read that as (2/5)x?

    On a normal day, Paul, 2 over 5x, without the parentheses or a space inbetween the 2/5 and the x.

    That's my argument. If we replace the quantity of (9+3) with the variable x, we have 48/2x. This would imply that 2 and x are multiplied together. Were it otherwise, it would read 48x/2. This is a good example of crappy notation and assumptions based on the writer of the expression's intent. Order of operations falls to pieces in this situation...do you solve this by the book, or with some algebra skills? The "proper" method, I think, will be based upon who you ask.

    It depends on how well they convey whether it's 2/5x or 2/5 x.

    Brackets first = 288, even Google says it's 288.
