# Semirngs¶

class sage.categories.semirings.Semirings(base_category)

The category of semirings.

A semiring $$(S,+,*)$$ is similar to a ring, but without the requirement that each element must have an additive inverse. In other words, it is a combination of a commutative additive monoid $$(S,+)$$ and a multiplicative monoid $$(S,*)$$, where $$*$$ distributes over $$+$$.
