How about a random math debate? - Paradox - 05-09-2012
Topic: Does 0.999... = 1?
Go.

0.999... does not equal 1, every number is different.
You wouldn't say 0.25 as 0.025??
RE: How about a random math debate? - noob007 - 05-09-2012
0.9... is equal to 1.
Why? Because it's a number infinitely close to 1. Therefore it is 1.
Another way to prove it:
1/9 = 0.1...
2/9 = 0.2...
etc.
9/9 = 0.9...
But 9/9 also equals 1, right?

"Because it's a number infinitely close to 1."
Yeah, but it isn't 1 is it??

It literally IS 1.

0.999 < 1
0.99999999999999 < 1
0.999... < 1
End...

0.999 < 1
0.99999999999999 < 1
0.999... < 1
End...
No, it is not the end. It may be hard to understand, but anything that's infinitely close to something _is_ that thing.
New topic: what does 1/0 equal?
RE: How about a random math debate? - Paradox - 05-09-2012
Say x = 0.999...
Then
10x = 9.999...
Take away x from each side (9.999... - 0.999... = 9)
9x = 9
x = 1

To me, anything/0 = i.

@Paradox's Question
x = 0.33333333
x * 10 = 3.33333333333
x * 9 = 3
3

@Noob007
1/0 = i
RE: How about a random math debate? - Paradox - 05-09-2012
How about this
0.333... = 1/3 right? And 1/3 * 3 = 1 right?
Well 0.333... * 3 = 0.999... = 1
