AddMonoidHom.mul

{R : Type u_1} → [inst : NonUnitalNonAssocSemiring R] → R →+ R →+ R

Multiplication of an element of a (semi)ring is an AddMonoidHom in both arguments. This is a more-strongly bundled version of AddMonoidHom.mulLeft and AddMonoidHom.mulRight. Stronger versions of this exists for algebras as LinearMap.mul, NonUnitalAlgHom.mul and Algebra.lmul.
