A semiring is a ringoid $\struct {S, *, \circ}$ in which:
That is, such that $\struct {S, *, \circ}$ has the following properties:
\((\text A 0)\) | $:$ | \(\ds \forall a, b \in S:\) | \(\ds a * b \in S \) | ||||||
\((\text A 1)\) | $:$ | \(\ds \forall a, b, c \in S:\) | \(\ds \paren {a * b} * c = a * \paren {b * c} \) | ||||||
\((\text M 0)\) | $:$ | \(\ds \forall a, b \in S:\) | \(\ds a \circ b \in S \) | ||||||
\((\text M 1)\) | $:$ | \(\ds \forall a, b, c \in S:\) | \(\ds \paren {a \circ b} \circ c = a \circ \paren {b \circ c} \) | ||||||
\((\text D)\) | $:$ | \(\ds \forall a, b, c \in S:\) | \(\ds a \circ \paren {b * c} = \paren {a \circ b} * \paren {a \circ c} \) | ||||||
\(\ds \paren {a * b} \circ c = \paren {a \circ c} * \paren {b \circ c} \) |
These are called the semiring axioms.
