In logic, Birkhoff's theorem states that an equality t = u is a semantic consequence of a set of equalities E, if and only if t = u can be proven from the set of equalities.[1]

According to Birkhoff's theorem, formal languages are considered to be models of natural languages. In mathematical logic, a person creates several classes of formal languages, to which first order logic and equational logic are of the highest importance. [2]

Equational languages are formal languages made up of countable variables, function symbols and an equality symbol. [3]

Equational logic can be combined with first order logic. Much of equational logic is derived from first order logic. [4]
