A **subring** is a concept in abstract algebra, particularly in the study of ring theory. A subring is a subset of a ring that is itself a ring under the same operations (addition and multiplication) defined in the larger ring. To formally define a subring, let’s consider a ring \\( R \\) with two binary operations: addition \\( + \\) and multiplication \\( \\cdot \\).
