You can't do the maths with infinite or reccurring numbers so you must start with a set amount of digits to prove a point. An absolute number.
Multiply by 10 simply moves the decimal point. It can't conveniently make more digits or decimal places
X = .999999
10x = 9.99999
10x - x = 9x
9.99999 - .999999 = 8.999991
Its not so much that your maths is wrong as it is that maths is wrong in general.
