The congruence relation satisfies all the conditions of an equivalence relation:. The modular multiplicative inverse is defined by the following rules:.

Thus, a multiplicative inverse exists for all a that are not congruent to zero modulo p. When the modulus n is known from the context, that residue may also be denoted [ a ].

Each residue class modulo n may be represented by any one of its members, although we usually represent each residue class by the smallest nonnegative integer which belongs to that class since this is the proper remainder which results from division.

Any two members of different residue classes modulo n are incongruent modulo n. Furthermore, every integer belongs to one and only one residue class modulo n.

Any set of n integers, no two of which are congruent modulo n , is called a complete residue system modulo n. The least residue system is a complete residue system, and a complete residue system is simply a set containing precisely one representative of each residue class modulo n.

Some other complete residue systems modulo 4 are:. The ring of integers modulo n is a finite field if and only if n is prime this ensures every nonzero element has a multiplicative inverse.

In theoretical mathematics, modular arithmetic is one of the foundations of number theory , touching on almost every aspect of its study, and it is also used extensively in group theory , ring theory , knot theory , and abstract algebra.

In applied mathematics, it is used in computer algebra , cryptography , computer science , chemistry and the visual and musical arts. A very practical application is to calculate checksums within serial number identifiers.

In chemistry, the last digit of the CAS registry number a unique identifying number for each chemical compound is a check digit , which is calculated by taking the last digit of the first two parts of the CAS registry number times 1, the previous digit times 2, the previous digit times 3 etc.

RSA and Diffie—Hellman use modular exponentiation. In computer algebra, modular arithmetic is commonly used to limit the size of integer coefficients in intermediate calculations and data.

It is used in polynomial factorization , a problem for which all known efficient algorithms use modular arithmetic.

In computer science, modular arithmetic is often applied in bitwise operations and other operations involving fixed-width, cyclic data structures.

The modulo operation , as implemented in many programming languages and calculators , is an application of modular arithmetic that is often used in this context.

XOR is the sum of 2 bits, modulo 2. The method of casting out nines offers a quick check of decimal arithmetic computations performed by hand.

Arithmetic modulo 7 is used in algorithms that determine the day of the week for a given date. More generally, modular arithmetic also has application in disciplines such as law see for example, apportionment , economics , see for example, game theory and other areas of the social sciences , where proportional division and allocation of resources plays a central part of the analysis.

Since modular arithmetic has such a wide range of applications, it is important to know how hard it is to solve a system of congruences.

A linear system of congruences can be solved in polynomial time with a form of Gaussian elimination , for details see linear congruence theorem.

Some operations, like finding a discrete logarithm or a quadratic congruence appear to be as hard as integer factorization and thus are a starting point for cryptographic algorithms and encryption.

The formula verifies a number against its included check digit , which is usually appended to a partial account number to generate the full account number.

This number must pass the following test:. Assume an example of an account number "" that will have a check digit added, making it of the form x:.

Each of the numbers , , , , , , , , , can be validated as follows. Alternately, you can use the same checksum creation algorithm, ignoring the checksum already in place as if it had not yet been calculated.

Then calculate the checksum and compare this calculated checksum to the original checksum included with the credit card number.

If the included checksum matches the calculated checksum, then the number is valid. The Luhn algorithm will detect any single-digit error, as well as almost all transpositions of adjacent digits.

It will not, however, detect transposition of the two-digit sequence 09 to 90 or vice versa. Other, more complex check-digit algorithms such as the Verhoeff algorithm and the Damm algorithm can detect more transcription errors.
