Poll: Solve a simple math problem

So a couple weeks ago I bumped into this math "problem":
1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1*0=?
[small](it has been recently pointed out to me that * is the sign for multiplication on the internet)
(and you would be correct to assume that there is a -1 in there as well)[/small]

The answer is pretty simple, I got it on my first try. But a lot of my friends and classmates couldn't solve it right away; and most of them are college students which is really sad. This is stuff you should study in middle school. Take a stab at it!

You sir, deserve a medal and everyone else that knows better than to divide be zero deserves a star. I wasn't paying attention (fuck!) but you're right it is multiplied.

I'm kidding, you don't get one.
Let's take another look at this, shall we?
1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1x0=?
1+1+1+1+1+1+1+1+1+1=10
10-1=9
1+1+1+1+1=5
9+5=14
and
1x0=0
so
14+0=14

Now this isn't done in the "correct" order but if you did it all in one step it would look like this:
10-1+5+0=14

PS. I guess this has been on the Escapist a couple times. Funny, it didn't come up when I searched for "convoluted math problems". But If you've seen this before and you are still getting it wrong you're, I don't know, retarded?

Also, I understand that this question is bullshit. I'm just pointing the shit of this "bull" out for all to see.

Divided by 0? I thought it was multiplied by 0. Dividing by 0 would get you undefined, even if you use the correct order of operations.

Edit: A lot of people are quoting me and telling me it wouldn't be infinity, it would be undefined. I s'pose I'll go with that, I'm no math expert.

If you meant for that divide sign to be a multiplication, it's sixteen. Otherwise, it's undefined.

EDIT: Wait a second, you snuck a minus sign in there, making it fourteen.

You kinda messed up a bit there. 1/0 means nothing really. Other than that if it is meant to be 1*0 then it is 14. This is not a simple Math problem it is simply a dirty trick to try catch people out.

The answer is minus infinity.
(1+1+1+1+1+1+1+1+1+1)-(1+1+1+1+1+1+(1/0))
=10-(6+infinity)
=10-infinity
=-infinity
If the end was 1*0= then the answer would be 4 as adding brackets the sum equates to
(1+1+1+1+1+1+1+1+1+1)-(1+1+1+1+1+1+(1*0))
=10-(6+0)
=4

Division by zero.

Exterminate! Exterminate!

EDIT: Now that it's changed, the answer is 14. Though I'd hardly call this a math problem.

EDIT 2 - The Editening: Damn, the Escapist is doing some weird things to my posts.

Inifinity, the last term 1/0 is defined as infinity, anything added or subtracted to that is also infinity.

EDIT: That divide is now multiply, so it's 14

Because the last thing is divided by 0, the last term is undefined, and you can't add other stuff onto undefined. So there is no answer. And yes, I see the minus sign in there.

EDIT: Ah, I see you fixed it. The answer is 14 if I counted correctly. It's easy to lose place in a long string like that.

I honestly just use this logic when faced with an issue like this.
Hey,if multiplying it by 0 is 0,it must work the other way around,right?

You can't divide by zero, mathematically speaking. So I thus conclude this problem has incorrect syntax-
Oh you fixed it.

1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+1X0
1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+(1X0)
1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1+0
=14

I just added brackets to show the order of operations. Also i refuse to use x as a multiplication symbol on a computer as this just confuses it with algebra.

Everyone who didn't get 14 should ask to get their elementary school fees back. Though I suppose you can miss the minus sign, so 16 wouldn't have been such a bad answer.
