mod

Represents the modulo operation or congruence relation in number theory and computer science.

Overview

Essential for expressing arithmetic relationships between numbers with respect to a given modulus, particularly in number theory, cryptography, and computer programming.

  • Commonly used to describe clock arithmetic and cyclic patterns
  • Fundamental in expressing congruence relations between integers
  • Critical for algorithms involving periodic behavior or wrap-around operations
  • Frequently appears in discrete mathematics and computational problems

Examples
