Spell it out for me.
Is zero really a number?
wehn you add 0.999... to 0 it becomes 1
>>8115421
Adding 0 to 0.999... Still makes it 0.999...
>>8115431
in (R, +) the following is true:
for all x in R, 0+x=x
Let x=0999...
Therefore 0+0.999...=0.999..
But 0.999..=1
therefore 0+0.999...=1 QED
define number
define really
>>8115356
define zero
>>8115438
>0.999..=1
that's like saying 2+2=1
>>8115356
No, zero is not a number, it’s a conspiracy to corrupt good, honest Christian Americans.
>>8115564
that's like, the joke
>>8115564
in Z/(4) anything can happen
>>8115742
>4
I'm retarded
meant Z/(3)
>>8115356
>Is zero really a number?
If it's not, what comes halfway between 1 and -1?
Is 1-1 = -1?
>>8115763
There's nothing between -1 and 1. Christ was born in AD 1. The previous year was 1 BC. QED
Zero is a jewish meme.
>>8115356
No. It's you OP. It's YOUR special designator in life. A big fat zero.

1/9 = 0.1111....
multiply by 9 to give:
9/9 = 0.999.....
thus
9/9 = 1
>>8115839
not rigourous enough
.999... can be definesd as
series from k =1 to infinity of 9(1/10)^k, which
is a geometric series. Hence it equals (9/10)/(1-1/10)=1
>>8115564
How? [math]0.\dot{9} = 1[/math] is true. One of the first things they teach to you in first term is the non uniqueness of the decimal representation of numbers, so having something like this shouldn't be surprising at all.
>>8116194
It's true i saw something like that in an online calculator
>>8116170
(9/10)/0 = 1 ?
>>8116194
>How? 0.9˙=1 is true
No. This is a Jewish scheme to fuck with the numbers behind economics.

It's also how they managed to turn a couple dozen Jews dying of typhod into 6 million.
>>8115431
1 + 0.999... = 2
The proof is trivial.
Why don't we leave the counting to things that don't need fractions?
>>8116204
go back to elementary/middle school when you learned about order of operations
>>8115356
If you agree that the naturals 1,2,3,4.... Are numbers and that the difference between any two naturals is a number, then zero is a number as well as the negative naturals.
