    [tex]Z_m = \{0, 1, 2, \ldots, m-1\}[/tex]

    for example,
    [tex]Z_2 = \{0, 1\}[/tex]
    [tex]Z_3 = \{0, 1, 2\}[/tex]
    [tex]Z_4 = \{0, 1, 2, 3\}[/tex]

    With addition and multiplication defined mod m (Z_m is not just a set).

    Warning: notation is ambiguous. I have also seen this used to mean the m-adic integers.
