Number Theory
Number theory is a branch of mathematics dealing with whole numbers and their properties. Prime numbers, divisors and Diophantine equations, among others, are important related concepts. Applications of modern number theory are numerous, including topics that range from elliptic-curve cryptography to music theory.
