The Chinese remainder theorem is widely used for computing with large integers, as it allows replacing a computation for which one knows a bound on the size of the result by several similar computations on small integers. The Chinese remainder theorem (expressed in terms of congruences) is true over every principal ideal domain.

Do not nd the solutions, but give explanation:

The preceding discussion allows us to deduce that the number of solutions the original congruence (1) is equal to the number of the solutions of the system of linear congruences (1)′. Since each of the variables in (1) ′are distinct, the number of solutions of (1) is equal to the product of the number of solutions of each ), the solutions of which involved thinking about remainders. It was tough though, because they did not even have the algebraic notation that we take for granted today. Even after the advent of Algebra, it took a couple of hundred years before Gauss in Europe, came up with the notation we use today for congruences.
