The zero ring is the unique ring in which the additive identity 0 and multiplicative identity 1 coincide. (Proof: If 1 = 0 in a ring R, then for all r in R, we have r = 1r = 0r = 0. The proof of the last equality is found here.) The zero ring is commutative.
What is not a ring?
If the ⋅ in (R,+,⋅) is associative without an identity, then (R,+,⋅) is not a Ring. It is referred to as a Rng. Here are two nice examples from the Wikipedia: A simple example of a rng that is not a ring is given by the even integers with the ordinary addition and multiplication of integers.
