A very important equivalence relation defined on the integers is called congruence modulo n. It is important because of a form of arithmetic that is associated with it. ... The equivalence classes are also known as congruence classes modulo n. Rather than say the integers i and j are equivalent we say that they are...

In mathematics, modular arithmetic (sometimes called clock arithmetic ) is a system of arithmetic for integers, where numbers "wrap around" after they reach a certain value—the modulus . Modular...

When working with congruence modulo n, the integer n is called the modulus. ... In a congruence modulo n, you can only divide through by an integer that is relatively prime to n. This is usually expressed by saying that...

This is used to give a short proof of Ramanujan's congruence p(11n+6) 0 (mod 11) and to prove the lacunarity of 10(z). Various related identities, many connected to Eisenstein series and some from Ramanujan's lost notebook, are established.
