Compound Reduction teaches to change any sum or quantity which consists of several denominations, to a given denomination; and to change a sum of one kind of money to a given denomination of another kind. When a sum or quantity, consisting of several denominations, is to be changed to a given denomination, work by the following RULE. Reduce the highest denomination to the next lower one, and this again to the next lower, and so on; observing to add to the amount of each denomination the number there is of that denomination in the given sum or quantity.
