Modular Arithmetic

Number Theory

Modular arithmetic is a system of arithmetic for integers in which numbers wrap around upon reaching a fixed value called the modulus, so that addition, multiplication and subtraction are replaced by the remainder of division by that modulus. A central property is that reducing modulo the modulus can be done after each operation or only once at the end of a computation, with the same result either way. The modern approach to number theory built on modular arithmetic was developed by Carl Friedrich Gauss in his 1801 book Disquisitiones Arithmeticae.
