COMPOUND SUBTRACTION.

COMPOUND SUBTRACTION is finding the difference between two numbers, of which one or both are compound. RULE.-Set the less number under the greater, as directed in Compound Addition. Then, beginning at the least denomination, subtract the under number of each from the upper, writing their respective remainders below them. But if the under number of any of the denominations be greater than the upper, add so many to the upper as make one of the next higher denomination; then take the under number from that sum, writing down the remainder as before, and carry or add one to the under number of the next higher denomination before you subtract it. The method of proof is the same as in Simple Subtraction.
