Example of Set of Residue Classes
The elements of $\Z_3$, the set of residue classes modulo $3$, are:
\(\ds \eqclass 0 3\) | \(=\) | \(\ds \set {\dotsc, -6, -3, 0, 3, 6, \dotsc}\) | ||||||||||||
\(\ds \eqclass 1 3\) | \(=\) | \(\ds \set {\dotsc, -5, -2, 1, 4, 7, \dotsc}\) | ||||||||||||
\(\ds \eqclass 2 3\) | \(=\) | \(\ds \set {\dotsc, -4, -1, 2, 5, 6, \dotsc}\) |
