i agree
.999... = 1
.999999... != 1

>> No.5236762

>>5236752
.999... = .999999...
OP's a troll, so I'm not going to respond to him. I'm not sure about you, though.

>> No.5236771

>>5236762
you would only think that if you were OP
nice try

>> No.5236776

>>5236773
both are equally obvious trolls
you would only have a bias if you were OP

>> No.5236773

>>5236771
What. This logic makes no sense.

>> No.5236786

>>5236776
Not necessarily obvious. I.. stupidly.. used to believe .333... was different from .33...

Wha.. How?

.999999... = x
9.99999... = 10x
10x - x = 9.9999... - .9999...
9x = 9
x = 1

This was back when I was 12 or so. I thought .33 was 1/3 and .333 was 11/33.. Which it is.. But.. I don't know. I was an idiot.

Yeah ok, i can sort of see that if you didn't realize that.

but what then was .3...?

Round it down to zero.

.999999...!=1!=1

0.999... = 1

Correct.

<span class="math">\displaystyle .99\bar{9} = 1[/spoiler]

<span class="math">\displaystyle .999 \neq 1[/spoiler]

Correct.

<div class="math">\frac{0.999999999999...}{0.999999999999...} = 1</div>

No because you didn't use all three generic proofs.
