How about the ring R=Z (the integers). Every element in the integers is a nonzero divisor and there is no way to get a multiplicative inverse, right? (since no fractions and no modulos and probably something else too)? Thus wouldn't any element of the integers be a nonzero element that we are looking for? Am I on the right track? | How about the ring R=Z (the integers). Every element in the integers is a nonzero divisor and there is no way to get a multiplicative inverse, right?
