WebIf Ris an integral domain and Char R= 0,then CharRmust be a prime number. For if CharR= n= rswhere rand sare positive integers greater than 1,then (r1)(s1) = n1=0, so either r1ors1 is 0,contradicting the minimality ofn. A subringof a ring R is a subset S of R that forms a ring under the operations of addition and multiplication defined on R. Web19. Special Domains Let R be an integral domain. Recall that an element a 6= 0, of R is said to be prime, if the corresponding principal ideal hpiis prime and a is not a unit. De nition 19.1. Let a and b be two elements of an integral domain. We say that a divides b and write ajb if there is an element q such that b = qa.
