Reminder that since the reals are equivalence classes of Cauchy sequences, the rationals are equivalence classes of pairs of integers which in turn are equivalence classes of pairs of natural numbers, it is strictly speaking incorrect to say that these number systems form a subset chain.

wrong. reals are uncountable infinity. to assume that they are a pair of naturals would be to assume they are also countable. learn math before making claims.

The rationals are isomorphic to a subset of the reals
You could just define them as such if you want to be nitpicky
Same is true for Z and N

N is a semiring, Z is a ring, Q is a field and R is a real closed field.

$ \boxed{ \mathbb{R} \, \boxed{ \mathbb{Q} \, \boxed{ \mathbb{Z} \, \boxed{\mathbb{N}} } } } $
