It depends on how you read the dash. If “/” means you divide what comes before it with everything that comes after, the answer is 1. If “/” only means that you multiply with 1 over the immediately following number it’s 9.
Personally I read the dash as being the former.

multiply and divide have the same priority, so you go left to right once you get it down to 6/2*3. so 9[/quote]

X2. This shouldn’t be that difficult
it’s 9

You can’t do Addition before Multiplication or Division.

You have to do parentheses first is what I have been taught that is why I get 6/6.
I agree with 9 - can’t get them convinced though.
See below:
2(1+2)
2(3)
6
=> 1
Whats’ wrong with this ?
as per my mate:
Not me.
The brackets give the right side of the expression precedence.
Hence solve for 2(1+2) first.
Gives you 6.
Then complete all other operations working from left to right
6/6
Answer: 1
I’ll go to my grave thinking this.
There’s no talking to me

Your right, now that I am looking at the problem like that it makes sense.
I repeat, it depends on how you read the dash. There is no right or wrong in this matter, it’s just a matter of convention.

But how does 6/2(1+2) get assigned to division being done before multiplication. And you going left to right.

How can there be 2 answers to 1 equation.
This is not philosophy 
Because it’s 2 different equations depending on what the dash means.

Now I am confused because I can see both ways being right.

To be clear by Dash what are you referring to ? The division sign the site won’t let me make ?

The ‘problem’ is that in text notation the divisor cannot be written any other way on the same line.
Computers require strict definition of operation notation, so we have come to define it was PEMDAS, left to right precedence on same level operations(MD, AS).
Voluminous showed the ‘other’ way of perceiving it, but the key was that he broke it down into a 2nd line.
6/2(1+2) = 9
6
----- = 1
2(1+2)
The difference is that you would write the second one into a program as 6/(2[1+2]).
Oh. That makes more sense. 6/2(1+2) is different than 2/(2[1+2]). Now I get it. Thanks red.
I’m referring to “/”. If it means that what follows is in a 2nd line, the answer is 1. If not it’s 9.
Hey Red why do you assign the (1+2) below the line ?
That is how my friend is doing it to.

A) It’s a slash, not a dash
B) No. There’s one meaning. If you want the ‘other’ way, it must be 6/(2*(2+1)).
C) Plug the original in any calculator and see what happens.
Has the internet really made people this stupid?
A)My mistake. Sorry about that.
B)No, there can be as many meanings as we want it to have. If I define “/” to be the integral symbol then this sure as hell ain’t 9, it won’t even be a number. The two meanings that make a lick of sense however are that “/” is either a simple divisor or that it means that whatever follows is in a 2nd line.
just broke out my old Algebra book, it is definitely 9. Thats what I get for over thinking a problem.
Lesson learned don’t over think math.
