Soit p premier et a entier avec a ≡ 0 (mod p) Alors pour tout c il existe une solution x de la congruence ax ≡ c (mod p), et cette solution est unique modulo p

A simple consequence is this: Any number is congruent mod n to its remainder when divided by n For if a = nq + r, the above result shows that a ≡ r mod n Thus
congruence
In general, we call the set of all integers congruent to a given integer a mod n a congruence class mod n It is easy to see that the number of congruence classes

Let a and b be integers and m be a positive integer. We say a is congruent to b modulo m if m divides a – b. We use the notation a ≡ b (mod m)
We read this as “a is congruent to b modulo (or mod) n. For example 29 ≡ 8 Prove: a ≡ b mod m and a ≡ b mod n
Definition: If a and b are integers and m is a positive integer then a is congruent to b modulo m if m divides a − b. • The notation a ≡ b (mod m) says that
Definition 1: Given m ∈ Z+ a ≡ b mod m if and only if m
Feb 22 2005 (b) a ≡ b (mod n) implies b ≡ a (mod n). Solution. The statement a ... m (mod p1p2 ···pk) for all m and all k ≥ 1. Solution. If m is a ...
Let a and b be integers and m be a positive integer. We say a is congruent to b modulo m if m divides a – b. We use the notation a ≡ b (mod m) to indicate
Nov 12 2014 a and b are said to be congruent modulo m
By the definition of equivalent modulo m this implies a = b (mod m)
Definition 3.1 If a and b are integers and n > 0 we write a ? b mod n to mean n
Definition 3.1 If a and b are integers and n > 0 we write a ? b mod n to mean n
Congruence. Definition. Let a and b be integers and m be a natural number. Then a is congruent to b modulo m: a ? b (mod m) if m
The next definition yields another example of an equivalence relation. Definition 11.2. Let a b
Integer a is congruent to integer b modulo m > 0 if a and b give the same remainder when divided by m. Notation a ? b (mod m).
22-Feb-2005 The statement a ? b (mod n) implies n (a ? b) ... m. The second step uses Fermat's Theorem. Now the congruence (*) means that:.
r = a mod d. Review: Modular Arithmetic. Let a and b be integers and m be a positive integer. We say a is congruent to b modulo m if m divides a – b.
