COMPOUND SUBTRACTION is the taking a lesser number from a greater, of divers denominations, and thereby finding the difference. RULE. Set down the lesser number under the greater, as in compound addition. Then beginning with the lowest number, subtract as in subtraction of whole numbers: when the lower number is greater than the upper, take it from as many of that denomination as will make one of the greater, and to the remainder add the upper number, set down the amount and carry one to the next, and so proceed till all are subtracted.

When the multiplier does not exceed 12. RULE. Begin by multiplying the lowest number first, as in integers; divide the product by that number which will make one of the greater: Set down the remainder, if any, and carry the quotient to the next number. When the multiplier exceeds 12, but is the exact product of any two factors in the table. |
