Ten times 2 are 20-20 farthings make 5 pence; set down 0 and carry 5 to the pence.

Pence.

Ten times 4 are 40, and 5 I carry make 45-45 pence make 3s. 9d.; set down 3s, 9d. which is the price of 10 pounds. Now multiply the price of 10 pounds by 10, the product will be the price of 100 pounds.

Shillings.

Ten times 3 are 30, and 7 are 37-37s. make 1 pound 17 shillings; set down £1 17. This product is the price of 100-Multiply it by 11 and you will have the price of 11 hundred.

Pounds.

Eleven times 1 is 11, and 9 I carried make 20-set 20 in

the place of pounds.

Thus we have £ 20 12 6 for the price of 1100 pounds. Now multiply the price of one pound by 11 and by 5, to find the price of 55 pounds-add this price to that of 1100 pounds, and you will have the answer.

Makes £21 13 1 2 the Answer for 1155 lb. Answer in words, Twenty-one pounds thirteen shillings and one penny half-penny.

When an Integer, that is, a whole number, costs so much a pound, what will a hundred weight cost?

RULE.

Multiply the price of one Integer by 7 and by 8, and the second product by 2: the third product will be the price of 112.

KEY TO CARD No. 19.

NOTE 1st.-A hundred weight Avoirdupois contains 112 pounds; consequently any number being multiplied by 7, and that product by 8, will make a product 56 times the first number; and this second product multiplied by 2, will make a product 112 times greater than the first number. 1x7=7×8=56 and 56×2=112.

Read thus, 1 multiplied by 7 equals 7, multiplied equals 56; and 56 multiplied by 2 equals 112.

Pounds.

Seven times 6 are 42, and 6 I carried are 48; set 48 in

the pounds.

This makes a product of £ 48 15 4 the price of 56 pounds-Multiply this sum by 2.

Pence.

Twice 4 are 8; set down 8 and carry nothing-twice 15 are 30—30s. make 1 pound 10 shillings; set down 10 for shillings, and carry 1 to the pounds.

Twice 8 are 16, and one I carried makes 17; set down 7 and carry 1-twice 4 are 8 and 1 makes 9; set down 9. Thus we have a sum of £ 97 10 8 for the answer.
