The principal ideal <3>= {0,3,6,9}
Consider the ring 2 Z= {......,-4,-2,0,2,4,6,.......}
The principal ideal <2> = {
....,-8, -4, 0, 4, 8, ...}
Note that in this case 2 # <2>. This situation arises since 2Z is not a ring

2.5 MAXIMAL AND PRIME IDEALS
In this section we are particularly interested in certain ideals of commutative rings.
ideals give us special types of factor rings. More specifically we would like to char
those ideals S of a commutative ring such that R/S is an integral domain or a field.
Definition 2.5.1
A proper ideal P of a commutative ring is said to be a prime ideal of R if whenever
Borbc P
