 Question 25274: 1) Let R and S be rings and define R x S = {(r,s):rES} to be the set of all pairs (r,s) with r ER and s ES. Define furthermore the addition and multiplication in R x S componentwise by (r1,s1)+(r2,s2)=(r1+r2,s1+s2) and (r1,s1).(r2,s2)=(r1.r2,s1.s2) a) show that R x S is a ring again. b) show that if R and S both have an identity element then so does R x S. c) show that R x S has non-zero, non-regular elements if R and S both are different from the zero-ring. d) Can R x S ever be a field?
