nope check my comment below for the answer
#29 to #26 - anon (01/04/2013) [-]
y = infinity
User avatar #30 to #29 - amegaara (01/04/2013) [-]
no then we could do:

y - y = 2 as in ∞ - ∞ = 2 and all math is ******
User avatar #107 to #30 - Soundtrack (01/04/2013) [-]
ah yes, good point.


#36 to #30 - anon (01/04/2013) [-]
would it not be _ i -i = 0_
because when you add or substract a number from_ i_ it's value still stays the same
but when you substract the same value throughout i
it will become nothing aka 0
User avatar #42 to #36 - amegaara (01/04/2013) [-]
what?
what i did is subtract y from both ends of the equation to make y-y=whatever
and when i did that i became infinity minus infinity equals 2 which is wrong which is why this mo fo has no solution
User avatar #101 to #42 - worstposter (01/04/2013) [-]
infinity minus infinity is in fact not 0, it can be anything you like, really.
lets say ∞ +2 = ∞, which is true
> ∞ - ∞ = 2
> 2*(∞ - ∞) = 2*(2)
> ∞ - ∞ = 4
therefore we can also say that infinity minus infinity equals infinity. because infinity plus infinity is still infinity. Its an irrational number.

y + 2 = y
2 = y - y
2 = 0
( 2 != 0 )
No Solution
User avatar #167 to #88 - babyanalraper (01/04/2013) [-]
Well, infinity = infinity + 2.
User avatar #190 to #169 - babyanalraper (01/05/2013) [-]
Are you really really sure about that? Would you please provide proof for that statement? You know, even an infinity + an infinity = an infinity. And then there are infinities of different sizes as well. For instance, an infinity made of all rational numbers is smaller than an infinity made of all irrational numbers, but all infinities composed only of rational numbers are equally big. Therefore, an infinity + 2 (rational) = an infinity.
#246 to #190 - seylorm (01/05/2013) [-]
but if we change your equation to the following: "2 = an infinity - an infinity"
so, no matter what these infinitys are they both have to be the same and therefore if you subtract them you'll get 0 and then the equation is "2 = 0" which isn't true so the answer is that there is no solution.
User avatar #267 to #246 - babyanalraper (01/05/2013) [-]
Actually, it would be (2 + an infinity) - an infinity = 0, which is completely correct.
#270 to #267 - flyslasher (01/06/2013) [-]
Infinity is the concept that a number is growing larger, so infinity/2 or infinity*2 or infinity+25 or infinity-1351321698654 are still equal to infinity. But nowhere in the original equation do we ever talk about infinity...
#102 to #88 - anon (01/04/2013) [-]
I think any solutions people found use cheats. (besides yours)
I thought of function, but the problem isn't written as such. [ f(y)=y+2 ]
#122 to #102 - anon (01/04/2013) [-]
No need since Y is the only variable you know you are trying to find Y therefor this man is correct.
#28 - simeonc (01/04/2013) [-]
Rearrange
Y = Y + 2
Programmers thinking:-
2, 4, 6, 8 etc

problem?
User avatar #99 to #28 - wiredguy (01/04/2013) [-]
main()
{

char subject;
cin >> subject;

if (subject = "programming") {
cout << "Good work soldier!" << endl;
}
else {
cout << "Keep your filthy programming out of this, it ain't relevant." << endl;
}
return 0;
}
User avatar #204 to #99 - asmodeu (01/05/2013) [-]
I'll take that and raise it up a bit:

typedef struct subjectlist
{ char letter;
subject
list *next; }

int main ()
{ const char subject = "programming";
subjectlist *compare;
subject
list *root;


dglfdlfd af
df l;gl slh p
fa df;a' df
a a;g ds;h;gd#s;h gfsh tsyoh kos[rth s
fd'glfsd

dfdajpfijadpi gjpsg pdksogh

return -1;}

I would advise against compiling this code though.
User avatar #209 to #204 - wiredguy (01/05/2013) [-]
Oh god what the **** x3

I just learned a bit of code as a personal project once, I have no idea what any of the sensical things there mean, let alone the (I presume) nonsensical parts.
User avatar #215 to #209 - asmodeu (01/05/2013) [-]
In order to fully understand the complexity of linked lists you will have to compile and run (multiple times if needed) the following code:

do {beer;}
while (sober);
User avatar #221 to #215 - wiredguy (01/05/2013) [-]
And then I realised do-while was a loop.

Well I'll be killing myself now.
User avatar #218 to #215 - wiredguy (01/05/2013) [-]
You could have just looped it, but it's understandable you didn't want to take the effort x3

And just, for clarification.
Do action "beer" (to drink a beer) while "sober = 1" (1 being true) right?
User avatar #228 to #218 - asmodeu (01/05/2013) [-]
Yes. Usually loops require something to be transformed into a boolean value {0,1}. When sober=0, the program may chose to stop looping "beer". Though it doesn't work for all compilers that way. Some end up in an alcoholic coma in hospital.
User avatar #243 to #228 - wiredguy (01/05/2013) [-]
Nicely put, 10/10
#106 to #28 - simeonc (01/04/2013) [-]
this only applies if there's a loop, otherwise its just 2
User avatar #163 to #28 - thumbsalad (01/04/2013) [-]
Y += 2;

Would be much more efficient though..

I don't understand what you mean.

There's nothing here to learn, just gibbering and a somewhat clever dick joke.
User avatar #105 to #91 - quietbrony (01/04/2013) [-]
im not serious, i said that because i actually wasn't learn math on the internet, just nonsense math, my use of reverse sarcasm was displaying my false stupidity, hence with the hoped result of creating laughter. Its quite complex humor really, im not surprised you are baffled.
#116 to #105 - wiredguy (01/04/2013) [-]
Your lame undertaking to confound me is evidence enough that you are not as of yet fully aware of my country of origin.
I am an Englishman, you see.
While the plashet of melatonin that once was known as my cerebrum has indeed been encumbered with your nebula of deceit, I see now the ironic sarcasm in your statement and stand up fully to accept the extent of my deserved ignominy.

My affluence of intellect has been stripped from me and I am left indigent of cerebral power in your eyes.
I only hope my considerable essay at making my vocabulary as eclectic as your own will make up for my shortcoming.

I extol your innovative use of ironic sarcasm, and I bid you good day.
#123 to #116 - quietbrony (01/04/2013) [-]
I too am a brit, and thank you for such a timely response, i admire the flair in your writing.
That second statement was also a joke, due too my humorous and clearly false explanation. I hope you had a jolly good laugh.
I am quite the punster today.
Good day.

LOL nothing.
it has some nice shops. Its a melting pot of humans from all cultures, ( yet a few white people still look at me and immediatly cross the road, then cross again when i turn around to look).

thats about it.
london is so overrated.
I just realised IOW is a quarter of the size of london alone.. thats ******* awesome.

This equation is per definition ******** .
#79 - cheezitman (01/04/2013) [-]
I guess I'm going to have to solve it sometime...

1y+2=1y (the reason I put 1y instead of y is because it is easier to solve)
Subtract 1y from both sides
2=0y
Divide by 0 on both sides
2/0=y
since you can't divide by zero it isn't possible
so y=Undefined
#80 to #79 - anon (01/04/2013) [-]
nope...
y+2=y
-y -y
2=0

User avatar #92 to #80 - mublerking (01/04/2013) [-]
you know in order to properly do this you separate it into left side and right side that way at no point will you have anything equal to something it isn't.
essentially:

LS. | RS.
y+2 | y

therefor LS =/= RS
Q.E.D.

At least in his method he put that y = 2/0 which is the next most correct answer.
User avatar #135 to #92 - gardenmanly (01/04/2013) [-]
"LS =/= RS"

but... the left side does equal the right side... that's how equations work
User avatar #142 to #135 - mublerking (01/04/2013) [-]
so youre telling me y+2 = y, that the right side IS equal to the left? which isn't actually possible except in the imaginary (so in this context its not possible because we're working as elements of the real number system)

y+2=/=y
y+2=y+2
User avatar #149 to #142 - gardenmanly (01/04/2013) [-]
ah **** ... I accidentally the whole thing...

forgive me, my brain went to mush, I thought you just meant in a proper equation, the left side does not equal the right side. I didn't know you meant this specifically and forgot that when solving things algebraically you do separate the sides.
User avatar #156 to #149 - mublerking (01/04/2013) [-]
its okay, happens to the best of us.
User avatar #148 to #142 - mublerking (01/04/2013) [-]
if we can always work in the imaginary numbers when discussing LS and RS then in theory every left side is equal to every right side.

Here we go. This goes for any of the commonly known sets of numbers in mathematics, namely the naturals, integers, rationals, reals and complex. For any element in the set (we'll call it x, and in this example we'll just deal with naturals,) there exists a unique solution to the equation x+a=x=a+x, meaning a is the identity element in respect to addition, or is the additive identity. In all of these sets, the additive identity is 0. That means that x+a=x=a+x is only true when a=0. Since this is a case where a=2, it can no longer hold true for any x in any of the above sets.

TL:DR: There exists no solution.
User avatar #38 to #19 - therianek (01/04/2013) [-]
what about derivation? it might work...
#70 to #38 - ipmules (01/04/2013) [-]
It's a common fallacy in differential equations that a solution to the derivative implies a solution to the original equations. Such is not the case. Think about f(x)=x^2+3 and g(x)=x^2+5. f `(x) and g `(x) are equal, but f(x) =/= g(x). There are cases in which y=y+2 does yield a solution, but only when 0=2. One example of this is under modulo arithmetic, namely (z mod 2.) In this case, y is congruent to y+2, but as modulo arithmetic is an arithmetic on the integers, you only have integer solutions. Typically when people are discussing problems like these, the assumption is that we're working under elementary arithmetic in the reals.

I am a math major, but haven't graduated yet and I believe that any of my fellow scholars would have no trouble coming to the same conclusion.

Y is a letter. It cannot be added to a number.
User avatar #72 to #62 - kinglobster (01/04/2013) [-]
y is a variable taking place of a number
User avatar #195 - thewalruss (01/05/2013) [-]
actually, Y = ∞...

∞ + 2 = ∞

By the way, that is not a infinity simbol... those are boobs.
