WebThere are some differences in exactly what axioms are used to define a ring. Here one set of axioms is given, and comments on variations follow. A ring is a set R equipped with two binary operations + : R × R → R and · : R × R → R (where × denotes the Cartesian product), called addition and multiplication. A ring is a set R equipped with two binary operations + (addition) and ⋅ (multiplication) satisfying the following three sets of axioms, called the ring axioms 1. R is an abelian group under addition, meaning that: 2. R is a monoid under multiplication, meaning that:
