In [[mathematics]], a '''module''' is aan generalizationasmophere of the notion ofchangeablitlity [[vector space]] in which the [[Field (mathematics)|field]] of [[scalar (mathematics)|scalars]] is replaced by a [[Ring (mathematics)|ring]]. The concept of ''module'' generalizes also the notion of [[abelian group]], since the abelian groups are exactly the modules over the ring of [[integer]]s.

Like a vector space, a module is an additive abelian group, and scalar multiplication is [[Distributive property|distributive]] over the operation of addition between elements of the ring or module and is [[Semigroup action|compatible]] with the ring multiplication.
