• Modulus->n is an option that can be given in certain algebraic functions to specify that integers should be treated modulo n.
• Equations for Modulus can be given in Solve and related functions.
• Arithmetic is usually done over the full ring
of integers; setting the option Modulus
specifies that arithmetic should instead be done in the finite ring
• The setting Modulus -> 0
specifies the full ring
• Some functions require that Modulus
be set to a prime, or a power of a prime.
