48/2(9+3)= ???

Go.

[Mrs. Xen_Warrior]

48/2(9+3)= ???

Go.

...ugh 2 :huh:

[Andrew_Pavlik]

48/2(9+3)= ???

Go.

lol thats easy, I'll break it down for you too! 48/2(9+3)= x. 48 divided by 2 is 24, so you have 24(9+3)=x, 9+3 is 12 so you have 24(12)=x, 24 x 12 is 288, 288 =x.

So easy, learn math!

*edit nvm, lets see what you think it is.

[chase]

Oh I know the answer, I'm seeing how long this thread will go on between those who think its 288 and others who claim it to be 2.

[Andrew_Pavlik]

Ahh, well I just edited my post with the order of operations, so that should help people! lol

[chase]

Well you may have fucked up my master plan.

[BladeTwinSwords]

48/2(9+3)
48/2(12)
24(12)
288

If this is your homework then shame on you.

[Mrs. Xen_Warrior]

Well then :lala:

[anex]

Look at you guys actually doing math.

288 (http://www.wolframalpha.com/input/?i=48%2F2%289%2B3%29)

I figured I'd try and get a huge discussion going.

It was done on another forum which is why I figured I'd bring it here :D

48/2(9+3)= ???


its 288....

you do the 9 + 3 first to get 12 then the equation is 48/2*12

order of operations has multiply and divide are considered the same step, so you have to work fro left to right

so u do 48/2 to get 24 and then u multiply it by 12 to get 288.



people are just to retarded to do simple math nowadays

[ZERO]

Well if this is a math question 288 if this is an accounting question it is anything you want. :smirk:

[acolyte_to_jippity]

writing pemdas like that confuses some people. they think that it goes
parentheses
exponents
mult.
div.
add.
sub.


when it's actually
parentheses
exponents
mult./div.
add./sub.

pem/da/s is more proper

[Steamer]

It's 288.

[Pink]

288 its left to right. So the answer isnt 2
The wierd thing my mom's forum has the same question on it.

[StarsMine]

and so does my facebook. I wonder what caused this to spread around the internet like this

[Steamer]

The same thing that causes everything else to spread around the interwebs.

teh lulz?

+ whining and a good argument.

[chase]

+ me?

[B1ackOut]

i got to the 2nd page on the bodybuilding forum before i couldn't stand how many people were getting it wrong

[elpolloloco]

I was convinced it was 288, but with the parenthesis... well it's been a while since I had to really focus on the order of operations so I was almost convinced it was 2.

My gut says 288. What do you do when in doubt? ASK GOOGLE.

You can enter math problems into the google search box and it will answer it for you.

Google says: 288

Problem solved :P

Here's the trick for those of you who thought 2. Everyone is saying parenthesis go first. Which is right. But even then you get:

48 / 2 * 12

The answer is 288 whether or not you do the parenthesis first. The problem is if you do the parenthesis first, your brain, since it's already on the right side of the problem, starts thinking that it should go from right to left.


http://www.mathgoodies.com/lessons/vol7/operations_exponents.html

48 / 2 * 12

/ and * are equal when it comes to the order they should be done, but a math problem STILL needs to read left to right.

Instead of 48 / 24 it's 24 * 12. It would only be "2" if it was 48 / (2 * 12). Patenthesis are not only used to override + and * preference, but to override left-to-right. And since everything in the parenthesis is done and gives you 12

48 / 2 * 12

There are no more parenthesis left so all operators being equal, go left to right

[SCRIBBLE]

I think this problem should be explained by a few more people.

X= can be anything, there is nothing to stop me from saying X=1 which would make your answer (-2)(2) which would be -4. If I use a X=2 theory then your answer would be (1)(-1) = -1 so on and so forth.

dont ask how i got it.

[Rosie]

If you solved it as 48/X(9+3) = 48/12X if x=2 then it is 48/ (2)12 which equals 2. The question as it is written is confussing. If you had 48/2*(9+3) it would be 288. But if the denominator is 2(9+3) it is 2, because you would solve the denominator before you divide. So is it 48/2 * (9+3) or 48/(2(9+3))?

...no.

just...no. you solve parentheses first, then exponents, then multiplication or division in order from left to right, then addition or subtraction from left to right.

that's basic math. like, 4th grade math.

-9x^2 + 30x - 25

The correct answer was right here, the very first post after the question. You can't solve for variables where the variable isn't given by pretending that the variable is a particular number. Welcome to basic algebra.

edit: Also, chuckles at the solution fail for the question in the OP.

What I meant was if the problem is
48
___
2(9+3) you cannot divide 48 by 2 withouth first solving for the denominator. Using a / as a division symbol screws up the look of the problem.

Fucking shit o.O your right, division symbol / <- works as a parenthisis

/ = fraction or ratio, generally follows all rules of division so we use it as that
- with the two dots = division we know from PEMDAS >.<

this equation should very well be clarified, we dont know if its

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

or

48
--- (9+3)
2

These are two completely different equations, but both could be applied to OP question

no. it's directly left-to-right. there is no clarification needed. any ambiguity as to the original intention of the problem does not effect the answer. the answer as it is written is 288.
