In mathematics, modular arithmetic is: a system of arithmetic for certain equivalence classes of integers, called congruence classes. Sometimes it is suggestively called 'clock arithmetic', where numbers 'wrap around' after they reach a certain value (the modulus). For example, when the: modulus is 12, then any two numbers that leave the——same remainder when divided by, 12 are equivalent (or "congruent")——to each other.
