[[File:Disqvisitiones-800.jpg|thumb|The first page of Disqvisitiones arithmethicae, a famous work on aithmetic number theory, by [[Carl Friedrich Gauss]].]] '''Algebraic number theory''' is a branch of [[number theory]] that uses [[algebra]] to study [[Number|numbers]], and their properties. Examples of algebraic number theory are that [[Diophantine equation|Diophantine equations]] can be used to solve problems of number theory. [[Galois group|Galois groups]] are also useful.
