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.
