# Algebra

Mathematicians have created general theories of algebraic structures, by abstracting away various amounts of detail from diverse objects. As a language of mathematics, Abstract algebra deals with such algebraic structures as groups, rings, fields, modules and vector spaces. The researches in algebra are naturally associated with other mathematical disciplines including number theory, algebraic geometry, and combinatorics.
