MULTIPLICATION OF DENOMINATE
NUMBERS, $97. 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.
9.98. When the simple number does not exceed 12.
1. 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.
QUESTIONS. $97. What is required when you are to multiply a denomi. nate number by a simple one ?
9.98. When the simple number does not exceed 12, how do you write it down ? How do you begin to multiply? How do you carry ?
d times 10d are 40d, equal to 3s 3 9 10 and 4d. Set down the 4d in
4 the lower line. Then 4 times
£12 36s 40d 9s are 36s and 3s to carry £13 19s 4d make 39s, equal to £1 and 19s over: set down the 19s. Then 4 times £3 are £12 and £1 to carry make £13. (2.)
