Hmm… the first three are the reals, but the last one is the rationals. Am I reading that right?
I’m really rusty on my set theory symbolism.
Can we get a plain English translation of each of these (probably don’t need a full interpretation, just “how would you read this aloud”).
Between negative infinity and infinity
x is a member in the set of x:es where x is on 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.
