HOW do you know that? Please define (for any sets A, B):

Sure, it's "obvious" for us. But how would you define "have the same number of elements" (in mathematical terms) such that it can be DEDUCED (!) für certain sets A and B?

If a = b = c, {a, b, c} still has "the same number of elements" as {3, 4, 5 }? :-P

Even if a = b = c = 1?
C'mon man! :-P
