The Modulus

Modulus, in mathematics, refers to the remainder left over after dividing one number by another. For example, when dividing 7 by 3, the quotient is 2 and the remainder is 1; the modulus of 7 and 3 is 1. It’s often written as 7 mod 3 = 1. Modulus is used in various fields like computer science, cryptography, and number theory to handle cyclical processes, check divisibility, or manage repetitions, helping to work with numbers within a specific range or cycle.
