obviously people who chose 2 suck at math

It's just written poorly, The way it's layed out I would say 2 but if it were written propperly (48÷2)(9+3) it would be 288.

even if its "layed" out poorly, doesn't change how you should calculate it
its more like 48/2*(9+3) -> 48/2*12 -> 24*12 -> 288

its layed out like how you would type it in a calculator,
like the one i use in engineering classes

Relax Einstein

it should be written:

48
----- = x
2(9+3)

OR

(48/2)*(9+3)

48
----- = x
2(9+3)

OR

(48/2)*(9+3)

dude, really, the first way gives 2, the second gives 288

Pretty sure in this format "48/2(9+3)" it will equal 2. You would use the distributive law to adjust the equation before really "doing the math".

a/b(c+d) would be distributed out to a/(bc+bd) = 48/(18+6)= 48/24 = 2

you don't distribute first, you need to calculate the parentheses first, then the /*, then the +-
so its exactly how i described it; 48/2*(9+3) -> 48/2*12 -> 24*12 -> 288

my 400$ calculcator will back me up on that

no one is going to school me on calculus, i do this shiit all day, its all i ever do in engineering

[Joker]

It's the fact that a/b(c+d) is equal to a/(bc+bd).

If I gave you 48/(9x+3x) would it equal 48/x(9+3)? Or 48/12x? and if x equalled 2 you would have 48/(12*2)=2?

lol work in the morning gtg, will be funny to see how this goes.

Edit, tried on my TI89 TI and got 288 so you may be right. I suppose this is why no one knows. The TI are notorious for working like crap woth brackets though so I'm still gonna stick with my 2.

lol i got it wrong, but now that i go back and think about it.

BEDMAS, simple as it gets, division comes before multiplication even after the brackets have been done.

BEDMAS ftw

BEDMAS ftw

lol that has nothing to do with it really. i was always taught Please Excuse My Dear Aunt Sally PEMDAS that would make the answer 2. But you have to consider with multiplication and division (the same goes for addition and subtraction) the order of operations is the same so you simply go form left to right. order of operations plays no role when considering multiplication/division or addition/subtraction

WRONG read my post

O YA! lets see you guys figure this out..EINSTEINS!
