0.999... is only a theoretical number.
So you think some numbers are only theoretical. So what are the non-theoretical ones?

]]>.99999... is just another way to write 1

Try 0.99999

]]>Well I used sound, thought-out search criteria. I found 9 (or 8.99999... if you prefer)
I'm talking about threads not posts. The latter may well be un-countable.
Bob
Which search criteria was it?

Welcome to the forum.
Your new thread brings the number on this topic to 9. Search on 0.99999 if you want to explore the many comments others have made.

I would say 99.999... is the number.

.999999... =1.00000000...

Just as long as it is not 8.9999999... That would be intolerable.

I like to think of it like this
.99999999... - .9999...
.9999... = .99999999... ( I just took a few measly nines out of those 3 dots) I call it 9 extraction from dots. After all there are gazillions of them in there and they will not be missed. Now it is easy to see
.99999999... - .99999999... = 0. You just have to remember ... - ... = 0. I call it m's law of the dots.
Using this great idea the proof you gave by multiplying by 10 works fine.
True.
