Between negative infinity and infinity

x is a member in the set of x:es where x is on the real line Nope, it is: x is a member of the set consisting of x itself and the real line.

The set of x:es where x is on the real line and the absolute value of x is greater or equal to zero

This one makes no sense… x is a member of the set cosisting the union of: the set of m/n where m and n belong to the integers, n being nonzero; the set x; and the empty set.

Last one makes no sense since x appear to be a set and a rational number at the same time. Implied by the meme it also supposed to be equivalent to the real line, which it is not.
