The directed graph of a commutative ring is a graph representation of its additive and multiplicative structure. Using the mapping (a,b) → (a+b,a ⋅ b) one can create a directed graph for every finite, commutative ring. We examine the properties of directed graphs of commutative rings, with emphasis on the information the graph gives about the ring.
