§6 Integers Modulo n
... In Example 2.3(e), we have defined the congruence of two integers a,b with respect to a modulus n . Let us recall that a b (mod n) means n|a b. We have proved that congruence is an equivalence relation on . The equivalence classes are called the congruence classes or residue classes (modulo n). The ...
