    Modular Arithmetic begins with a modulus "\(n\)", \(n\) must be a member of \(\mathbb{Z_+}\).

    Modulus "\(n\)" divides all the integers into congruent or residue classes. These classes are determined by the remainder after division.

    The modulus must always be set in advance; for example \(n=2, n=5, n=15.\)

    Remainders are always \(0,\cdots, n-1.\)
