The latter operation is the most interesting one and creates a complicated structure on integer numbers. Modular arithmetics synonyms, Modular arithmetics pronunciation, Modular arithmetics translation, English dictionary definition of Modular arithmetics. n. A form of integer arithmetic in which all integers having the same remainder when divided by a given natural number are considered equivalent: Clocks use 2018-01-28 · Lecture 2: Modular Arithmetic and Historical Ciphers by Christof Paar. Modular arithmetic: Goal: Computation in finite sets (used in about 95% of modern cryptography) Finite sets are often represented in circles, e.g. the hours on a clock face. [Definition of modulo operation, from Understanding Cryptography] The remainder is not unique.

The numbers go from to , but when you get to " o'clock", it actually becomes o'clock again (think of how the hour clock numbering works). So becomes , becomes , and so on.

Let n be a positive integer. We denote the set [ 0.. n − 1] by Z n. We consider two integers x, y to be the same if x and y differ by a multiple of n, and we write this as x = y ( mod n), and say that x and y are congruent modulo n.

MODULAR ARITHMETIC 2. DEFINITION : • Let a, b and n are integers and n > 0. We write a ≡ b mod n if and only if n divides a − b. n is called the modulus. b is called the remainder. 2021-04-13 · Modular arithmetic is the arithmetic of congruences, sometimes known informally as "clock arithmetic." In modular arithmetic, numbers "wrap around" upon reaching a given fixed quantity, which is known as the modulus (which would be 12 in the case of hours on a clock, or 60 in the case of minutes or seconds on a clock). Modular arithmetic Much of modern number theory, and many practical problems (including problems in cryptography and computer science), are concerned with modular arithmetic.
