You don't get it do you?
If we return to http://www.internationalskeptics.com/forums/showpost.php...ostcount=11598 which deals only with Cardinality, then aleph1 – aleph0 = aleph1 + aleph0 = aleph1 > aleph0 > 0, where the result aleph1 is a meaningless result because "+" and "–" are are indistinguishable.
No you still don't "get it" and evidently simply don't want to get it.
Again if you think “"+" and "-" are indistinguishable”, that is just your problem.
So is "μ + σ" one of your "valid expressions"?
