The idea in this chapter is to use congruence to split up the set ℤ of integers into a finite collection of disjoint subsets, think of the subsets as objects, and then see if the arithmetic operations on ℤ can induce arithmetic operations on the new objects in a way that makes sense. To see how this might work, we first look at two examples.
