Depends on the order of operation. It could be 1 or 9. :devil

x=9
I hope so, anyways...

YOU DIVIDED BY ZERO!!!
RUN FOR YOUR LIVES!!!!!!! :O

9

P.E.M.D.A. says it's 9.

BEDMAS, you mean?
Or PEDMAS, in french?

P.E.M.D.A.S. is what we use here B-17

I suppose it's the same thing... doesn't really matter which order you do the DM/AS by, does it?
-
Sorry but no math on break :lol

:lol Forgot the S.
So what's the joke anyway?

There is only one order of operations.
-

Well I kinda figured as opinionated as everyone is here that people would say its either 1 or 9. Some people say to do the implied 2*3 taking authority over the 6/2. 2(3) ia treated as single unit or "number" and is handled as a chunk.
edit: speeling
-
Some people ignore the order of operations, that makes them incorrect.
-
6 / 2 (1+2) = x
6 / 2 (3) = x
6 / 6 = x
x = 1
Besides PEMDAS, remember that when you are dividing, you complete all equations above and below the division sign before you actually divide.
-
You should have divided 6/2 instead of multiplying 2(3). The mistake I think you're making is you're thinking of 6 being over everything after it like
6
---
2(3)
But that isn't the case, it's really (6/2)*3. Or
(6*3)

:huh :huh
How do you come up with that assumption?
Original equation was : 6 / 2 (1+2) = x
Which means:
6
-------
2(1+2)
Just like a book, math is read left to right. With the addition of the parenthesis to 1+2 you have to assume that the 2 is attached, and you must complete the equation on the bottom before proceeding to divide.
In order for the equation to work as you state is would have to look like this:
(6/2)(1+2) = x
Then! Would x = 9, but because there is an absence of a parenthesis around the 6/2, you must assume the equation as I stated above.
-
Yeah, and there are no parenthesis around 2 (1+2) to indicate it's one number 6 is divided by. (1+2) is the first operation as dictated by the parenthesis, so we have 6/2(3). Now follow your own rules and read left to right, 6/2 and then multiply by 3.
6 / 2 (1+2) means
6 (1+2)
-------

I say 9x :devil

PEMDAS :
Parenthesis, Exponent, Multiplication, Division, Add, Subtract.
6/2(3)
Parenthesis: 6/6
6/2(3)
Multiplication: 6/6
In order for the equation to work as you state is would have to look like this:
(6/2)(1+2) = x
Then! Would x = 9, but because there is an absence of a parenthesis around the 6/2, you must assume the equation as I stated above.
-
The equation does look like (6/2)(1+2), you don't assume anything is attached to anything in math, you follow the order of operations.
6 / 2 (1+2).
Parenthesis?
6/2(3) Check.
Now in the absence of parenthesis you multiply or divide (whichever operation it happens to be) in the order they appear left to right.
3(3).
9.
edit:
6/2(3)
Precisely, you treat 2(3) as multiplication...because it is. This is the same as writing 6/2*3, if that makes it more clear.
-
Omg Flipperk.
6 / 2 (1+2 ) = x
Six, divided by two, TIMES 3.
Six, divided by two. 3
TIMES 3 = 9
x=9
-
correct
now...
3*4^(-1/3)/2=x
x=?

You must take care of ALL parentheses first. Then do the basic stuff, so 1+2 = 3. 2(3) = 6. 6/6 = 1
-
the real question is.
should we be helping people with their math homework on these forums??? :noid

Wow...my hair hurts now..

math......hate the stuff
math is a religion created by man to block in your mind and not allow it to expand to new idea's
like when you go to school and sit in rows......when you line up 2by2....ect ect
everything is about numbers..... it suppresses the side of your brain that is for imagination and free thought.

2(3) is not a parenthesis operation, it's just multiplication. You are distributing.
@ink, there are topics in math that require extraordinary imaginative abilities to get comfortable with, not to mention all the kids driven by their imaginations after seeing the moon landings or some episodes of star trek to become engineers and change the world.

I was being a bit "tongue in cheek" but
in reality a structured thought process does inhibit the freethinking imagination takes.
one side of the brain processes differently then the other side, the side that does art and imagination(if I remember correctly its the right side) is not the side that does math and structured problems.
nothing in math could be considered "imaginative"
I would be interested in hearing how you came up with that :aok
-
I just plug the formula into excel and let it do the work. Frees my brain up for pondering the mysteries of the cosmos. Or killing it with beer.

quit drinking about 16 years ago...cant stand beer/alcohol and/or drunk people.
people that drink and don't turn into complete idiots I don't mind.

If you take math to merely be 1+2 or think mathematicians are some kind of walking calculators you'd be right, but they aren't. Tell me it doesn't take imagination to picture in your head a counter example to the converse of the mean value theorem. Proofs take a large amount of imagination and creative thinking. Most math isn't as simple as being given an equation and solving it using simple algebra, that's only what most people ever learn or have to use. Calculus is taught as plug and chug in high school even, when there is a great deal more to it.
"Our imagination is stretched to the utmost, not, as in fiction, to imagine things which are not really there, but just to comprehend those things which are there" - Feynman
Math requires the thorough understanding of many concepts and identities in order to prove things, and you won't thoroughly understand them if you can't imagine them in their entirety, probing for weak points and searching for the bits that are vital to functionality.
Many times it's useful to approach difficult problems by imagining the graph first. Or try to imagine the ridiculous multidimensional space you're working in :).

I read that article, I would like to read the books they talk about....
I can see where you and they are coming from...like trying to imagine the number "2.2 million light years" (i believe that's the closest galaxy to us..Andromeda) or even what traveling at the speed of light for a year is.
my point is that it is a real number, with a math equation it will always comes out to the same sum....
with imagination the end results (the sum) is never the same.
take two people and give them a math problem, as long as they do the math correct you will always get the same answer.
ask the same two people or a hundred people...ask them to make up a story about a boy and his dog......every story will have a different ending hell the whole story will most likely differ
this is why I say there is no imagination in math.
a great book to read is called "Drawing from the right side of your brain" great book for those who want to draw but cannot....chances are they had the side of the brain for imagination suppressed.

Yes, if you give them a math problem out of a standard textbook maybe.
Give two people something to prove that isn't trivial, you will get plenty of variation :).
There is even variation in solving those standard problems some times, there were a few nice questions in AP calc back in high school where you could go about it slightly different ways.

I'll have to look into that book..

I think alot of people confuse arithmetic with maths.
you dont have to get very deep into maths before creativity and imagination become very important. eg. calculus is pretty procedural until you get to evaluating integrals, then you find out whether you're a mathmetician or not :uhoh

btw Google displays the precedence for you if you need to check it ;)

I thought excel was invented for math..
Write the formula, check it against known answers with different variables, and viola.. you never have to think about it again.
