No you aren't

.9r * 10 is 9.9r

There is no changed value

Because the answer is still an infinity...

THink of it this way, for you, I am not thinking of this way

.9r is closest to 1
that must mean
9.9r is closest to 10...

in your theory

So how is the value changed?

Google in

"0.9 repeating equals = 1"

and see what you get...

Regular people just don't get it, becuase they use commen sense, but all the mathmaticians...They no its equal...Thats the difference
