Abstract: Abstract The direct product R = x i∈ R i of a family of semirings {R i | i ∈ Ω} has the structure of a semiring with the operations of addition and multiplication defined componentwise. This semiring is additively- [resp. multiplicatively-] idempotent [resp. zerosumfree, simple] if each of the R i is additively- [resp. multiplicatively-] idempotent [resp. zerosumfree, simple]. It is not entire if Ω has order greater than 1.
