Suppose R is a ring with 0 = 1. Then by the previous proposition we have x = 1·x = 0·x = 0 for all x ∈ R. Thus R = {0}. This ring is called the zero ring. Thus if R is a ring other than the zero ring, then 1 6= 0 in R. Since 0·x = 0 for all x ∈ R, we conclude that 0 is never a unit in a nonzero ring.

WebTo show that F is a field we need to show further that F is a division ring; i.e., for each s 6= 0 F in F, the equations sx = 1 F ≡ e has a solution in F. From the multiplication table we see s = e , x = e ⇒ sx = e s = a , x = b ⇒ sx = e s = b , x = a ⇒ sx = e , So F is a commutative division ring; i.e., a field. 3.1.5.
