CASE 2. When the multiplier is above 12, and produced by any two numbers multiplied together, multiply the multiplicand by one of the numbers first, and the product by the other ;-then the last product will be the answer
If no two numbers will produce the multiplier exactly, multiply by two such numbers as come nearest to ir ; then multiply the multiplicand by the difference between the multiplier and product of the two nume bers, and add this product to the last product; if the product of the two numbers were less than the multiplier ; but if more, subtract, and the result will be the

COMPOUND DIVISION. Compound Division teaches to divide a number of several denominations.
CASE 1. When the divisor does not exceed 12, begin at the highest denomination, and find how many times the divisor is contained in it ; which, being found, place under its own denomination ; and if anything remain, reduce it to the next less denomination, to which add the number in that denomination, and divide as before; so proceed thro' all the denominations of the dividend.
If the divisor be above 12, and produced by the multiplication of two small numbers, divide by one of the numbers, this quotient again by the other; and the last product will be the answer.
EXAMPLES. 1. If 6 yards of broadcloth cost £.4 6s. 6d. what will 1 yard cost?
6 6 price of 6 yards.
5 price of 1 yard.
In this example, finding I cannot have the divisor in the first denomination, which is pounds, I reduce it to the next denomination, or shillings, and add in the 6 shillings, which make 86, in which the divisor is. contained 14 times, and 2' remain ; I set down 14, and reduce the 2 shillings to pence, adding in the 6 pence, which make 30 ; then finding the divisor is, contained 5 times in 30, I set down 5, and the work is done.
