Thought of this during Maths, its c00l!
kk, follow this
0.9999999.... (repeater) = 10a
0.099999999... (... means repeater) = 1a
0.9999999... - 0.099999999... = 0.9
10a - a = 9a
0.9 = 9a
a = 0.1
10a = 1
Therefore: 0.999999... = 1
1 - 0.99999999... = 0.000000000000000...1
10a - 10a = 0
Therefore: 0.0000000000000...1 = 0
0.0000000...1 = (1/infinity)
Therefore (1/infinity) = 0
Therefore Infinity x 0 = 1
Now, i really cant see why this isnt true, but i dont think it is. Proof seems all correct...

The equation (1/Infinity)=0 seems okay to me but how come the equation (Infinity x 0)=1 can be correct?Because I know that if you reverse the equation it's true but I have learned this (Any number x 0)=0 no matter what the number is.So we can say that it is true and that it is not true at the same time because, (1/Infinity)=0 so (Infinity x 0)=1 but (Any number x 0)=0 so (Infinity x 0)=0 Now I'm getting myself confused  |

Can't get my head around this O____O
So you are saying so called 'infinity' starts with a 1 and a infinite number of zeros.
infinity = 1 x 10c
where c is an infinite number.
Using your previous statement:
That means 0= 1 x 10-c
infinity x 0
= (1 x 10c) x (1 x 10-c)
= 1 x 100
=1

Wait, MP is right.Cause 10=1, 20=1 so it's basically 1 x 1=1.I've gotta be more attentive during Math class....

How about we define a number for infinity? Or is it plainly 0.0000000...1?x0=1?

Uhhh...I like to think the statement 'infinity x 0' was in meaning infinity (a one followed with x amount of zeros) and zero (same number of zeros including the one before the decimal point followed by a one). Which makes one. Also, 0.999999..does make 1. O___O One third is 0.333333... therefore 3 thirds is? |

Which infinite? Positive or negative. So technically what you're saying is that
+inf * 0 = 1
-inf * 0 = -1
That's pretty much a load of crap--but I see where you're coming from. Since you substitute 1/inf to be .00000...1 then you are saying just by rounding down it will equal 0. Okay--I can live with that. I can live with rounding down. So I'll live with 1/inf = 0. But you simply can't go by: Multiply both sides there's the answer.
You can't say something like
1/9000000 = 0
(That's .000000001 or something, essentially the same thing)
And then say 9000000 * 0 = 1.
What are we gonna do next, divide by 0?

It's not rounding down, it's using algebra. Your thesis is incorrect by using 1/900000000 as an example.

ISN'T anything times 0,0?
its what my teacher said!
we don't even know what inf.is!
1)secondly a nano second is curently the fastest second meaning a nanon might be an unknown numeral
2)the length of space...huge and unforgiven...so vast it has infinity breaking distance!
(edit 1 to the 0 power? that's 0
example:2 to 2 power : 4 2x2 ;aka 2 2's multiplied...
10 to the 10th power is 100
10 to the 100th is 1,000
10 to the 1000th is 10,000
10 to the 10000th is 100,000
10 to the 100000th is 1,000,000(million)
10 to the 1000000th is 10,000,000(billion)
10 to the 10000000th is 100,000,000(trillion)
10 to the 100000000th is infinity (aka the number no one knows)

It's because although 1 and 0.999.. appear different they are the same number! The same goes for 0.000.. ..1, and the reason is that they are infinitely close to 1 and 0 respectively. Which infinite? Positive or negative. So technically what you're saying is that +inf * 0 = 1 -inf * 0 = -1 That's pretty much a load of crap--but I see where you're coming from. Since you substitute 1/inf to be .00000...1 then you are saying just by rounding down it will equal 0. Okay--I can live with that. I can live with rounding down. So I'll live with 1/inf = 0. But you simply can't go by: Multiply both sides there's the answer.

He doesn't round down, he proves that 0.000.. ..1 = 0, which is true. |

AHA! This is known as a flawed mathematical proof!
Anyway, if 0.000...1 = (1/infinity), then it also = (0/infinity). That means 0=1!!! And that is wrong!
Im sure i could eventually find what's wrong, but in the meantime, remember that you cannot divide by 0 and that most proofs involving infinity are flawed.
EDIT:
I pretty sure i know what's wrong. You say that 0.000...1 = (1/infinity) but it doesn't as 0.000...1 has an infinite progression of zeros, and when that happens, it means the 1 at the end does not exist!!!
By stating that 0.9999... = 1, you say that 0.000...1 = 0 not (1/infinity)
Therefore 0.000...1 = (0/infinity) not (1/infinity). Anyway, as one person said once, you cant expect numbers like 0 and infinity to behave like normal numbers...

^^^ thats what i was thinking. I thought it was sorta cheating to round up and down like that.
