# Abstract algebra

**Abstract algebra**is the field of mathematics concerned with the study of algebraic structures such as groups, rings and fieldss. The term "abstract algebra" is used to distinguish the field from "elementary algebra" or "high school algebra" which teaches the correct rules for manipulating formulas and algebraic expressions involving real and complex numbers.

Historically, algebraic structures usually arose first in some other field of mathematics, were specified axiomatically, and were then studied in their own right in abstract algebra. Because of this, abstract algebra has numerous fruitful connections to all other branches of mathematics.

Examples of algebraic structures with a single binary operation are:

- semigroups
- monoids
- quasigroups
- groups

- rings and fieldss
- modules and vector spaces
- associative algebras and Lie algebras
- latticess and Boolean algebras
