^Damn, I registered 15 days after you. And you're 13.

I'm 14. I signed up when I was 11.

It's odd that my posting style was VERY similar to NFG back then.

Really?

When I see you, I remember your math threads.

I dont see NFG dping that. O_o lol XD

Well, 0.99999.........................................................

is equal to one.

Hmmm. Should I bump that thread, create a new one, or let it die?

It is not if you know something about derivatives and integrals (are those the names in english? i forget)

0.9999..... repeating for infinty IS equal to one.

Do I have to school you with elementary proofs?

I wanna see you try.

x=0.999....
10x=9.999....
10x-x=9.999... - .999...
9x=9

x=1

16-36 = 25-45

16-36+(81/4) = 25-45+(81/4)

(4-(9/2))2 = (5-(9/2))2

4-(9/2) = 5-(9/2)

4 = 5

See? I can use your false math to do whatever I want!!!!

The mistake comes when you take the square root of the two sides (I think that's what you did). There are TWO square roots, a fact you seem to miss.

I don't know what the hell is happening though. Make it look neater.

EDIT: I don't know what the fuck you did. The 36 and 25 disappear, there is that random two for some reason, and it is too messy for eyes.

Tsc, tsc. And I thought you knew math.

Make it neater for god's sake. That is an insult to math visually and logically.

Im joking, dtewi. Heres why its wrong:

 

The square root of a number elevated to square (again, not sure on english) is the module of that number. So:

(4 - (9/2))2 = (5 - (9/2))2

You cant just remove the square and eliminate the 9/2. Actually is this:

!4 - (9/2)! = !5 - (9/2)!  (! stands for the module)

!-0,5! = !0,5!

0,5 = 0,5

See?
