Semiring is an algebraic structure equipped with two binary operations. For instance, if the two binary operations are classical addition and multiplication then o and 1 are identity elements with respect to addition and multiplication respectively in the ring of integers. In case if monosemiring, both binary operatiobs has the same identity. Now i am looking for the possibility of a semiring other than monosemiring to have a common identity with respect to both binary operations. If possible, an exapmle in the support will be appreciated.
