Cute.

The integers form a PID, so every finitely generated projective module over them is free (source: https://math.stackexchange.com/questions/162945/submodule-of-free-module-over-a-p-i-d-is-free-even-when-the-module-is-not-finit )
This implies that [math]K_0 ( \mathbb{Z} ) = \mathbb{Z}[/math] as the other anon pointed out, doesn't it?

No, just the shitty ones.
