### Re: This Is Not Tom

Thanks for posting this! It's an amusing site. Fair warning: the source for the final clue has changed making it unsolvable without cheating. I was lucky enough to stumble across it early on before things got changed up. Spoiler: mathclass.php will be a dead end If you want the answer (that no longe...

### Re: A very interesting Mathematical Paradox

I think I have it...not sure though: 1/E = 0.000...1 1+(1/E) = 1.000...1 1+(1/E) = (E+1)/E 1.000...1 * [E/(E+1)] = [(E+1)/E] * [E/(E+1)] = 1 Yes? So 1 exists in at least three phases. And this would mean 1.000...1 = 0.999... ? If so...so weird. But this CAN'T be right. I think all I did was multiply...

### Re: A very interesting Mathematical Paradox

I like this, it kind of twists the mind.

So since 0.999... = 1, and intuitively 1 - 0.999... = 0.000...1, then does 1.000...1 = 1? Can't think of a way to test that.

### Re: A very interesting Mathematical Paradox

NVM...

I just posted a query as asking if .8999... = .9

I should have actually tried to work it out. It's correct.

8/9 = .888...

1/9 = .111...

1/90 = .0111...

.888... + .0111... = 0.8999...

8/9 + 1/90 = 81/90

81/90 = 9/10 = .9

.8999... = .9

Sorry!

### Re: A very interesting Mathematical Paradox

I can accept this. Now what I'm wondering is does:

0.8999... = .9

?

0.8999... = .9

?
