Is 0.999… = 1?

Is 0.999… = 1?

Well. Some people say yes. Some people will say no and explain that the radical number 0.999… is approaching 1 but is not 1. The value should be somewhere near to 1 but is not exactly 1.

So, is 0.999… = 1?

I not sure but there is a simple proof that supports the claim.

Let $x = 0.999 ...$ (1)

Multiply (1) by 10,
$10x = 9.99 ...$  (2)

Then (2)-(1):

$9x = 9$

$x = 1$
