Damn, you are stubborn.
I would admit it if I was wrong. I am not.

Go and ask your teacher.
"How many different numbers are equal to the number 17?"

Ask yourself as well:
Is 16.9999(9)9 = 17?
Is 16.9999(9)9123 = 17?
Is 17.0000(0)01 = 17?

If what you are saying is true, than there are an infinite number of unique numbers that are equal to 17.
Say that outloud and think about how rediculous it sounds.

A number is either 17 or 'not 17'.

you don't understand what infinite is it seems...
anyway, you see mathematical proof but this isn't enough, so i can't say anything anymore :D
Just :

16.999999 indefinitely = 17
17.00000 indefinitely = 17
BUT
16.99999(9)123 != 16.9999 indefinitely != 17
so, no, there is only one 17, but you can write it a lot of different ways. But you can't understand and you don't want to understand, so... stay in your little life :D

That was my last message, no need to talk to someone that have no arguments and don't want to see the truth^^ it's like talking to a fanatic religious :D

So you are saying that there are 3 numbers equal to 17?
And then you claim that I am the fanatic?
:D

No, only one, since 17.0000000(0) and 16.99999(9) are basicaly equals to 17.
And thats not something you see

Thanks :) But I think he
