You Too Can Be A Math Genius
I always liked the following proof:
_
[1] x = .999
_
[2] 10x = 9.99 [multiply by 10]
[3] 9x = 9.0 [subtract [1] from [2]]
[4] x = 1.0 [divide by 9]
_ _
But, in [1], we have x = .999, therefore, .999 is exactly
equal to 1.
Please don't start a discussion on what is "wrong" with this,
I know what is wrong with it. However, at a first glance,
it is rather surprising.
