Only idiots would say it's false...
2019-06-17 16:34
actually, it's wrong.
You need + 0.111... to get the 1
2019-06-17 16:37
Actually it isn't equal.
The value 0.999... approaches 1 but actually it isn't.
The decimal expansion of 1 is obviously 1 or you may write 1.000...
Both expressions aren't same but tend to be equal when sufficiently large amount of 9s are taken.

He's right, here's the proof:
1/3= 0.333333
so 0.333333*3= 1, not 0.999999
You can make a quick google search, there are a ton of good explanations why it's like that

2019-06-17 17:48
x=0.9999.....
10x=9.9999.....
10x-x=9.9999...-0.9999...
9x=9.000...
9x/9=9.000.../9
x=1.0000
x=0.9999
0.9999...=1
1=0.9999....
2019-06-17 17:54
999 is not equal to 1000
so why 0.9999999999 equal to 1
it's not
2019-06-17 17:54
1/3 = 0.333...
2/3 = 0.666...
3/3 = 0.999... ,but also 3/3 =1, therefore 0.999... = 1
2019-06-17 18:01
yes it is, we learn this in 8th grade.
2019-06-17 18:02
But what if I have the following calculation?
1 - Infinitesimal
The result should be 0.999999999999999999999999999
but if 0.999999=1 then the result should be 0.9999999999999999999999999999.....99998
and that doesnt make sense to me.
2019-06-17 19:44
So on a graph .999... will touch the 1 line? That is what .999...=1 means.
2019-06-17 19:50
Oh look, how cute...a "point 9 repeating" troll.
Let's see...where to start...your linguistic definition of infinity is not exactly relevant. As soon as you agree that a number like pi can have infinitely many digits (which I doubt you dispute), then we could change each of the digits after the decimal point to a 9 and get our "point 9 repeating" number. That concept exists completely independently of how you write it (with the dots or whatever) or of the English word "infinity" (which, incidentally, mathematicians use sparingly--mostly as the adjective "infinite" to describe sets). Lofty philosophical concepts of what infinity might mean have little to do with precise mathematical definitions.
If I had stopped writing the numbers, they would have rounded?? Numbers don't round by themselves. People round them because they decide they can ignore some of the digits for whatever purposes they currently require.
It looks like you're claiming that "point 9 repeating" not only doesn't equal 1, but that it's also not a rational number. That must mean that one-third of it ("point 3 repeating") is also irrational. But you didn't seem to think that the number 1/3 is irrational.
Holes in my math, huh? How about you bring my post and your response to 10 random mathematicians, and see whose they pick as having holes. Since your basic problem seems to be that infinity is too mystical to be quantified in algebra, I'll even grant you 10 highly spiritually inclined mathematicians.
You have also not answered the very basic challenge: If you claim that "point 9 repeating" doesn't equal 1, then the burden falls on you to find me the number halfway between the two. When you manage that, I'll listen more closely.
I'm not the one hiding behind algebra; you're the one hiding behind vague, non-mathematical definitions.

true
if you see price in store 0,99$ you actually pay 1$ cause 1 cent means nothing
2019-06-17 19:54
you piece of shit...
World Population Clock: 7.7 Billion People.
99.9999% of 7700000000 = 7699992300.
So, 7700000000 - 7699992300 = 7700.
Only 7700 smart ppl in the world.
2019-06-17 20:14
No, it's just 0.9999999999....
2019-06-17 20:31
0.999... = 0.(9) = 1
1/3 * 3 = 3/3 = 1
1/3 = 0.(3)
3/3 = 0.(9) = 1
can't explain better

Haha I love this meme men)) ofc is true but also
false = true
2019-06-18 01:40
0.99999 = 0.1111111111111111011
2019-06-18 11:50
how does a number equal a number that the first number is not?
2019-06-18 11:52
+1 it's the same as 1+1/2+1/4+1/8+1/16+1/32+...=2. You can use the same way to prove both of these.
