The set of all congruence classes of the integers for a modulus n is called the ring of integers modulo n, and is denoted , , or . The notation is, however, not recommended because it can be confused with the set of n-adic integers. The ring is fundamental to various branches of mathematics (see § Applications below). The set is defined for n > 0 as: WebModular multiplication. 🔗 In Theorem 3.4.10 and Theorem 3.4.14 we had seen that addition and multiplication and mod work nicely together.

WebIn modular arithmetic, the integers coprime (relatively prime) to n from the set of n non-negative integers form a group under multiplication modulo n, called the multiplicative group of integers modulo n. Equivalently, the elements of this group can be thought of as the congruence classes, also known as residues modulo n, that are coprime to n .
