| May 1, 2010 at 21:03 | comment | added | François G. Dorais | Having read the above comments, let me clarify that by ring I mean a not necessarily commutative ring with identity. The fact that $\mathbb{Z}$ is commutative can be seen by applying induction to the subset $X = \{x : \forall y (xy = yx)\}$ of $\mathbb{Z}$ and realizing that $X$ is closed under negation. | |
