How do you think?
48÷2(9+3) = 2 or 288
Pole has been created. Comment on that question, please.

i think it's 2

wtf?

it's 2, how do you get 288?
-
48÷2(9+3) = 2 or 288
( ) First. So 9+3 = 12. This is still between ( ), so you do 2 * 12 = 24. Then 48/24 = 2.
And the wrong way:
48/2 = 24, then * (12) = 288.
You always need to calculate the ( ) first, then / or * and after that + and -. That is why the second answer is wrong imo.
-
obviously it's 2!

wtf?

Was gonna vote 288, then reminded myself that you have to open the brackets first. Rule says so.
-
48/2(9+3) = 48/2*(9+3) = 24*12= 288
/ * are equal according to priority order
to make 2 it's 48/(2(9+3)) => more () to force priority to the invisible * (of 2*(9+3) )
-
I'm (2+25*4-V4+0²/5)% sure the correct answer is 2.
-
288 is the correct answer. multiplying and dividing are equal, so you divide 48/2 1st because its infront

288 is correct
-
Your argueing is interesting. 50% wrong 50% correct.
We'll see what rest thinks.
-
maybe some buggy calculator or pc fail and answer 2 ???
-
48/2(9+3) = 48/2*(9+3) = 24*12= 288
-
i think this way:
48(9+3)/2=(48*12)/2=288
48/2(9+3)=48/(2*12)=2
48/2(9+3)≠48(9+3)/2
So, the answer is 2.
Btw nice thread crom :D
-
i trust Bootsyou cause he is maths teacher :P
-
48÷2 * (9+3) =
24 * 12 = 288 (real answer)
if the answer is 2 then it has to be like
48 / ((9+3) * 2) =
48 / 12 * 2 =
48 / 24 = 2
-
my mind = blown
-
same thing with 5 - (2+3)
if we calculate 5 - (2+3) equals 0
but if we remove quotes () it will be 5-2+3 which equals 6
hope i cleared it up

order of operations!
i've seen quite a few of these on facebook mostly with something like 5 + 5 + 5 + 5 + 5 + 5 x 0 having 0 as the most popular answer "cos anything times 0 is 0!" which is true but you do multiplication/division before subtraction/addition so you do 5 x 0 first THEN the rest. and if that's too tough for you just use wolfram alpha :L
-
the parenthesis are already * or x . eg: 2(5)=10
48/2(9+3)= X
48/2(12) = X
48/24 = X
2 = X
X=2
-
Why are you guys putting number 12 into brackets after adding numbers. There is not point in it I guessss? That's why you give the wrong answers.
-
48/2(9+3) = 48/2*(9+3) = 24*12= 288
troll maths btw corrects is 288

:-X

A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right.
288.

288

48÷2(9+3)=48:2(12)=48:2x12=24x12=288

We know the outcome. Locked.
