WebModular Arithmetic. 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. We may omit ( mod n) when it is clear from context. Every integer x is congruent to some y ... Web4 okt. 2024 · It's hard to avoid the topic of modular arithmetic, when discussing the Affine Cipher.
