It's the set of all rational numbers Q ("integer fractions") where we remove ( ∖ denotes a set difference) all natural numbers { 1, 2, 3, …. }. If 0 ∉ N, 0 is still rational so 0 ∈ Q ∖ N but many more numbers are in that set: − 1, − 2 for starters and also proper fractions like 1 2, 113 355 (and their negatives) etc. It's not hard to see that these rational functions in π π form the smallest subfield of C C (or R R) which contains π π and $\Bbb Q. Here, the key is that Q(π) Q ( π) is isomorphic to Q(x) Q ( x) as fields, they're not the same thing per se.
