48÷2(9+3) = ??? -- VOTE!! Poll Added

Random thought, if you use PEMDAS your answer will be = 2 (Yes, I am under 25 years of age =P )

If you make the equation into a fraction then your answer will also be = 2


Everyone who gets 288 just seems to be doing out the equation left to right, which I don't believe is the correct way to do it. Maybe it is just the way we were taught though....

More thoughts

2(12) comes before 48/2 otherwise the problem would look like this: (48/2)(9+3)

Scotty, remember PEMDAS does not mean you do Multiplication before you do Division.

Then put the friggen equation as a fraction!!!

Im not going to lie, i have no idea what this equation is. Thats the problem with pure math degree and leaning towards finance instead of physics. What I can tell you, is that in the equation

GPH = Q / (8.33lb/gal)(T2-T1)

if GPH = Q divided by everything,

then the proper mathematical syntax would be

GPH = Q / ((8.33lb/gal)(T2-T1))

You are absolutely correct.

And because that's the way I think, I can't come up with anything but 2 for an answer.

to me the 2 is (2), meaning (2)(9+3) with the brackets being implied, as if this was a transposed equation

as it's written, the answer is 288


By the way, for the curious American, not only are those equations on wrappers, they are on every draw you enter, or, it says "Prize will be awarded upon completion of skill testing question." Usually the liquor store draws have the "Skill Testing Question" on them, and the answer is scribbled somewhere on the box :lol:

If you write it as a fraction then you are correct. But that is NOT the original expression

48
__
2(12)


IS NOT, repeated, IS NOT

the same thing as

48/2*12.

48
__
2(12)

is the same thing as

48/(2*12).

Then we shall agree to disagree.

I made it algebraic, where x=3

16x
_____
2(x + 3x)

then

8x
_____
x+3x

then

8x
_____
4x

then x cancels, and 8/4 = 2

A horizontal fractional line also acts as a symbol of grouping:

So

4/5+5

is not

4
5+5

And because this is computer and I write everything, I assume the above

Its 288, using PEMDAS it breaks down like this

48/2(9+3)

48/2*12

24*12=288

Multiply and Divide and equal, just like Add and Subtract. you go in the order of the problem, not multiply then divide

If you used PEMDAS it would be 2*12 not 48/2 therefore giving you 2. ::facepalm::

Both my parents, who are grade school teachers said the answer is two.

One of my family members is a high school math teacher. They said 288

Regardless, it's a very interesting debate.

I believe in Calculus you learn to first simplify the equation. I don't think multiplying the 2 by the items in the ()'s count as "Order of Operations" as much as "Simplifying the Equation".

That calculator says 2, and I believe it. Simplifying the equation precedes Order of Operations.

There are some great posts in here, and I haven't had time to read everything.

But the people substituting 2(12) for 2 x 12 seem to me to be doing it wrong.

If you could simply replace the parentheses with a multiplication sign, then why not do this:

16 ÷ 4^2 = 1
(that's 4 squared)

could just be rewritten 16 ÷ 4 x 4 and then the answer should be 16, which is obviously wrong.

I scored a 5 on the AP Calculus exam.
I received 770 out of 800 on the SAT.
I posess a degree in both Physics and Math.

The answer is 7.

 

[rehmus]

you know what would be a great way to settle this? a poll...

oh.
