NOTE. If the price be any even number of shillings, multiply the quantity by half the number, doubling the first figure of the product for shillings; the rest are IV. When the quantity is compound. RULE.-Multiply the price by the number of integers (if any), find also the value of the inferior names by taking aliquot parts; this value added to the price of the integers will be the amount of the whole. V. When the quantity is a mixed number. RULE.-Find the value of the integral part, by the former rules; find also the value of the fraction by multiplying the price by the numerator, and dividing the product by the denominator; the sum of these values will be the answer.
