what is LIM anyway... all i know, thats my surname lim is my surname...one said:But I think it's not correct just to say
0.999... = 1
because it isn't 1, even if you go on writing nines forever.
As far as I know you have to write
lim 0.999... = 1
which is correct.
(But I'm not sure if what I wrote is correct. )
Erm good luck... when might i learn this?Insano said:lim means limit. What it says is what the value is going to be at infinity.
I have to learn about this for my math exam this Monday. Wish me luck. It's a bit more complicated though.
We proved 0,99... = 1 in the third grade.Azner said:Erm good luck... when might i learn this?

I was tought in the 11th year of school here in Bavaria, don't know what the equivalent in your countries is.HunterSeeker said:High School maybe? In the Swedish equilent of high school I was tought about lim.

Now:
If 0.999...=1
then
1.888...=2
Why should 10 - x = 9x.Mr Stabby said:10-x = 9x
9.999...-0.999... = 9
Check the bold line.Mr Stabby said:0.999... = x
10x = 9.999...
10-x = 9x
9.999...-0.999... = 9
9x = 9
x = 1
Insano said:Check the bold line.
You already use the thing you want to prove in your first lines. What you're saying is that 10 x = 10
Sulkdodds said:But where exactly does all this 1.888 bullshit come from?
So I suppose you want it this way:Mr Stabby said:sorry that's a spelling mistake should be 10x - x
Erm, am i the only other person here thinks like this, what i consider consider normal. 0.999... is equal to itself, thats its value? It's not 1 because thats a different value.Danimal said:0.999... = 1 on a calculator only because it dosen't have enough space to store all the nines, so it rounds it.
0.999... = 0.999...

Unless you've invented a new system where any number equals another one. Lets go all the way! 1 = 5000 (im rich!)

bbson_john said:0.9999... means 0.9999 with infinite 9, not 0.9999.
15357 said:0.11111..... = 1/9
Raxxman said:Anotherway to look at this:
the gap between .9 recuring and 1 is infinitely small.
As an infinitely small gap doesn't exist, neither does the difference between .9 recuring and 1
