A subset I Z is called an ideal if it satisfies the following three conditions: (1) If a;b 2 I, then a+b 2 I. (2) If a 2 I and k 2 Z, then ak 2 I. (3) 0 2 I. The point is that, as we will show now, the ideals in Z are exactly the subsets of the form nZ. In other words, the sets of the form nZ are characterized by the

Thus \(R/N\) is a field, so for any \(x \in R \setminus N\) we have \(x y \in 1 + N\) for some \(y\). Since the sum of a nilpotent and a unit is itself a unit, we have that \(x y\) and hence \(x\) is a unit.
