WebMODULAR ARITHMETIC 3 By Theorem2.4, there are jmjincongruent integers modulo m. We can represent each integer modulo mby one of the standard representatives, just like we can write any fraction in a reduced form. There are many other representatives which could be used, however, and this will be important in the next section. 3. Modular … WebIt is usual to study cryptography in terms of numbers rather than letters. To do so, we need to use modular arithmetic. Modular arithmetic is concerned with ﬁnding the remainder of integer division with respect to some other given integer n, called the modulus. When you divide any integer by n, the remainder is always an scottish planning framework 4
