If only you all had put as much effort into learning mathematics in school as you have put into arguing a trivial and pointless thing related to primary school mathematics.

Nope, it is ambiguous.

To give a better example,
"The man saw the women with the telescope"

Who has the telescopes, the man or the women?

Half the people are arguing one way, half the other.
 
OK, so everyone who's been to school says it's 9.

Everyone who's a professional mathnerd says it's not clear.

So my question is - how should it be written, such that it's clearly 9?

I'm enjoying the disparity in the arguments:

Camp 9: It's 9 you uneducated morons! Any fool with a D in GCSE maths knows this!

Camp 1: It could be either, but if a problem like this appeared in my degree level maths the answer would probably be 1.
 
The correct answer is to write the original equation in a proper mathematical form, not in an ambiguous way. When has ÷ ever been used in algebra?

But this more about the state of todays education, people are bunging numbers left right and centre into a spreadsheet and coming up with and answer and maintaining their answer is correct and not questioning what is in front of them.

If that was a question set in front of me I'd write out both answers showing how the original question could be interpreted both ways as it is not clear what it means.
 
What? Of course it's one! Just in the same way that 6x/2(3y*4z) = x/4(yz)

I know I do a maths degree, but still? Can no one remember Bidmas?

Brackets Indices Division Multiplication Addition Substaction?

You do it in that order, therefore the answer is one!

Can we have a harder question please? I need to start revising :)

6 / 2 * 2 = 6
6 / 2^2 = 1.5

but 2^2 = 2*2

Maths is broken

And writing everything on one line is retarded.

Read my post :)

Indices comes before division, whereas multiplication comes after division, therefore you do it before multiplication :)

Just because 2*2=2^2 does not mean that x*x=x^x

It seems that "of course it is 1" doesn't quite work in this thread, those who used BODMAS come to the answer 9. Of course equally "of course it's 9" doesn't quite work either because of the strange way the equation is formed.

The actual right answer appears to 9 or 1 depending on how you the equation is written, and it is written in a purposely ambiguous way so that people will argue incessantly on the internet.

I don't think it matters one jot whether you have a Maths degree or not, it is ultimately a pointless argument over equally valid interpretation.

In my humble opinion.

Thats just a fail equation and has nothing to do with what i posted.

Brackets are there for a reason, to avoid this confusion, and writing mathematical formulae on one line of ascii text is hardly 'industry practice'

No, you put 2*2=2^2, so I put that just because of that does not mean x*x=x^x :)

I know it doesn't matter :)

But surely as there are brackets and a division sign then you would have this:

6/(division)2(multiplication)(1+(addition)2)(brackets)

Therefore you complete the content of the brackets first: 1+2 = 3
Then you multiply the coefficient of the bracket by the bracket itself (something that my school, sixth form and university teachers have always told us to do, as it is part of the brackets): 2*3 = 6
Then you complete the division: 6/6=1

I understand that the equation is written very ambiguously, but I can't see any other solution :)

And yes Castiel you are right, I'm just waiting for Mr. Postman to deliver me some prezzies, and this is more fun than playing cod :)

You are still not making any sense, where did i ever say it does? I think you are just confused by the abundance of 2s :p I could have written 2^3=2*2*2. It just so happens in the special case you have written is valid where x = 2
