no then we could do:

y - y = 2 as in ∞ - ∞ = 2 and all math is ******

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

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

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.

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.

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.

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

y + 2 = y
2 = y - y
2 = 0
( 2 != 0 )

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.

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.

Actually, it would be (2 + an infinity) - an infinity = 0, which is completely correct.

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...

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;

return -1;}

I would advise against compiling this code though.

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);

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?
#228 to #218 - asmodeu
Reply +1
(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.

Imo i would use derivation on this...
y+2=y
first derivation:
f(x) : y+2 = y
f(x)' : 1 = 1
because derivation from y is 1 and derivation from 2 is 0

Problem solved

A derivative, put simply, is how fast an equation is changing. The derivative of y=3x is dy/dx=3 because y is changing by 3 every time x changes. The derivative doesn't say anything about the actual solution to the original equation the way you're doing it. You're just proving that the rate at which y is changing is equal to the rate at which y is changing. Plus the way you did it was wrong because you don't know the derivative of y, so what you really would have is y'=y'.

Except that didn't really solve it, since you didn't even adress the equation itself.
You didn't even try to adress it as an equation. Equations are solved by finding the values of the variable(commonly x, but here it's y) for which both sides are equal.
Functions on the other hand is finding the output for different values of x.
An example of an equation is 2+x=2x with the solution being x=2. Equations can exist for which there is multiple solutions. An example is 1=x^2 with both x=1 and -1 being valid answers
An example of a function is f(x)=3x+7 with there being a different output for each value of x. Functions can exist where certain values of x is invalid. An example is f(x)=1/x with x=0 being invalid.
As a sidenote f(x) means function of x, so for your invalid attempt you should've written f(y).

Also my "attempt" at solving this.
y+2=y
2=y-y
2=0
No valid answer.

He should have left the f(x) part out all together. The y+2=2 is all the notation you need.

I know that equations don't use that kind of notation, but just because the mistake would've been removed if he correctly adressed it as an equation instead of a function, does not mean that the mistake shouldn't be pointed out.

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

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.

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

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.

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.
