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. We may omit ( mod n) when it is clear from context. The modulo operation (abbreviated “mod”, or “%” in many programming languages) is the remainder when dividing. For example, “5 mod 3 = 2” which means 2 is the remainder when you divide 5 by 3. Modular arithmetic, sometimes called clock arithmetic, involves divisibility and congruence, and examines the remainder. Because the standard method for telling time is to split the day into two 12 hour segments.

We use modular arithmetic daily without even thinking about it. When we tell time, we use hours on the interval 112. And when the clock gets to 12, we don't wonder what is going to happen next, we know that the hour "wraps around" to 1 and starts over again. This is modular arithmetic. From basic algorithms like Sieve, Bitwise-sieve, Segmnted-sieve, Modular Arithmetic, Big Mod to Primality test, CRT etc. all other advance number theory algorithms.

In 1796 he did some work that advanced the field, and in 1801 published the book Disquisitiones Arithmeticae which, amongst other things, introduced congruence modulo and the ≡ symbol. Modular arithmetic is a system of arithmetic for integers, which considers the remainder.

Innan vi ingår i klargörandet av betydelsen av termen aritmetik, kommer vi att värden ), modulär aritmetik (som fungerar med moduler) och ordinal aritmetik

We ended up at 0 so . With a modulus of 2 we make a clock with numbers 0, 1. We start at 0 and go through 7 numbers in a clockwise sequence 1, 0, 1, 0, 1, 0, 1.

Modular Arithmetic – Basics As you know that modulo operator (%) computes the remainder obtained on dividing an integer a by a positive integer c. For example, 9 % 8 = 1, 5 % 3 = 2 and − 1 % 5 = 4. If you didn’t understand the last example, then, please refresh you knowledge of negative integers by positive integers.

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

a ≡ b(mod n) ⇔ a −b = k · n, för något k ∈ Z Vid implementation har vi a = b · a b + a mod b eller a = b · (a div b)+a % b där (a div b) har I matematik är modulär aritmetik ett system för aritmetik för heltal , där siffror "sveper" när de når ett visst värde, kallad modul . Det moderna tillvägagångssättet för modulär aritmetik utvecklades av Carl Friedrich Gauss i sin bok Disquisitiones Arithmeticae , publicerad 1801. Modular Arithmetic. Let n be a positive integer.
