Math problem...

[Goober Mcfly]

Could one of you math wizards explain how this works to me?

         x=y
        xx=xy
     xx-yy=xy-yy
(x+y)(x-y)=(x-y)y
       x+y=y

let x=y=1

2=1

Dividing by zero to get from line 4 to line 5 invalidates the logic.

 

[Peeping Tom]

If x = y the first four arguments are valid. The fifth can never be valid excepting the trivial solution, as it violates the law of identity.

Cool.

Now what's the largest prime number? Hmm?

 

[Peeping Tom]

M39 is the largest prime number found to date. It is formed from the expansion of (2^13466917)-1 and is 4053946 digits long. It's name M39 designates it as a Mersenne prime, which have the form 2^P -1. This type of prime will always be the largest since there is a particular algorithm which allows for testing of large candidates given the (relatively weak) power of computers at this point in time.

I take it from x+y=y.

x+y=y

x=(y-y)

x=0

Since x=y (from the beginning)

y=0

x+y=y (when both x and y are zero).

Your problem, like every problems in life, is your assumption x=y=1.

The proof is complete

Is this related in any way to the Celebrity Death Pool? If not, I can't help.

Oh Man

I've got a slow computer and I don't know the largest prime number! Damn, not a good day.

OTB

Your problem is that you assume that x=y=1 from the beginning.
The transfer from line 4 to line 5 is impossible if x=y=0.
(You cannot divide by 0).

I know the answer

The Answer is 42 , the mice told me while I was hitchhiking accross the galaxy

Between x and y, who's got the biggest tits?

 

[MuffinMuncher]

I also like pie

Biggest Tits you say:

If an grade eight class has a blond, a brunette and a redhead, who has the biggest tits?

The blond 'cause she's twenty years old.

Someone asked a question, clearly directed my way. Since I knew the answer offhand, I replied. In a polite manner I might add.
