MULTIPLICATION OF DENOMINATE NUMBERS. 1. Charles pays 6d for a pencil : How much will buy two pencils? How much will buy 3 pencils ? 4 pencils 5 pencils ? 6 pencils ? 2. James puts 1 quart and 1 pint into a measure: How much could he put in a measure of twice the size? In a measure of three times the size? 4 times the size? 5 times the size ? 6 times the size ? 3. What is the product of 2s 4d multiplied by 2? by 3 ? by 4? by 5? by 6? by 7? by 8 ? by 9? 4. What is the product of lyd. Iqr. multiplied by 2? by 3? by 4? by 5 by 6? by 7 ? by 8? by 9 ? 5. Multiply E3 9s 10d by 4 ? In this example we say, 4 times 10d are 40d, equal to 38 and 4d. Set down £ d the 4d in the lower line. Then 4 times 3 9 10 9s are 36s and 3s to carry make 39s, 4 equal to £1 and 19s over: set down £12 363 400 the 19s. Then 4 times £3 are £12 £13 19s 4d and £i'to carry make £13. We may conclude from the examples that, to multiply a denominate number by a simple one, is to repeat the denominate number as many times as there are units in the multiplier. OPERATION. CASE I. § 73. When the simple number does not exceed 12. RULE. I. Write down the denominate number and set the multiplier under the lowest denomination. II. Multiply the lowest denomination by the multiplier, and see how many units of the next higher denomination are contained in the product, and set down the excess as in addition. III. Multiply the next higher denomination by the multiplier and add the units to be carried from the last product; then reduce the sum to units of the next higher denomination, write down the excess and proceed in the same way for all the denominations, setting down the entire product when you come to the last. Q. What is required when you multiply a denominate number by a simple one ? When the simple number does not exceed 12, how do you write it down? How do you begin to multiply? How do you carry ?

CASE II. $ 74. When the simple number is greater than 12 and a composite number. RULE. Multiply the denominate number by one of the component parts, or factors, and then multiply the product by the other factors in succession : the last product is the one required. EXAMPLES. 1. Multiply £6 2s 9d by 48=6X8. Ans. £294 12s. 2. What will 24 barrels of flour cost, at £2 lls 8d per barrel ? Ans. £62. 3. What is the cost of 42cwt. of tallow, at £1 14s 6d per cwt? 4.

CASE III. § 75. When the simple number exceeds 12 and is not a composite number. RULE. Multiply the simple number by each of the denominations separately, and reduce each product to the highest denomination named. Then add the several products together, and their sum will be the answer sought. EXAMPLES. 1. Multiply £5 3s 8d by 13. 13 13 8d 38 39s=£1 19s. 88 80 13 £5 £65 2. Multiply £6 8s 9d by 139. 139 x9d = 1251d=£ 5 4s 3d Ans. £894 16s 3d. 3. Multiply £0 2s 4d by 195. Ans. £22 158. 4. What is the cost of 46 bushels of wheat at 4s 710 per bushel ? 5.
