COMPOUND NUMBERS. Any number expressing things in the same name or kind, is called a simple number; as 60 men, 45 years, &c.

But when a number expresses things of different names or kinds, it is called a Compound number ; as 56 pounds 4 shillings and 6 pence; 3 years 4 months 25 days ; 5 miles 3 furlongs, &c.

Different names or kinds are called different denominations.

COMPOUND ADDITION. Is the adding of several numbers together, having differént denominations.

RULE. 1. Place the numbers so that those of the same name or denomination may stand directly under each other.

2. Add the first column, or lowest denomination, as in whole numbers; then divide the sum by as many of the same denomination as make one of the next greater, setting down the remainder under the column added, and

carry

the quotient to the next superior denomination ; continuing the same to the last, which add as in simple addition. I.

Sterling Money. În England, Money is reckoned in pounds, shillings, pence, and farthings, which is called Sterling Money.

TABLE.

12 pence

S.

4 farthings (qrs.) make i penny, marked d.

make 1 shilling; 20 shillings

make 1 pound, £ Note.-Farthings are often written as the fraction of a penny ; thus, 1 farthing is written d., 2 farthings, d., 3 farthings, d.

EXAMPLES.

1. Add together £74 13s. 6fd.; £18 5s. 7d. ; £24 10s: 9 d.; and £13 8s. 4 d.

Operation. Illustration.—We find by adding up the

20 12 4
3. d. gr.

column of qrs. the amount is 7, which we 74 13 6 2 divide by 4, because 4 qrs.=1 penny, and 18 5 7 0 the quotient is 1 penny, and the remainder 24 10 9 3 is 3qrs. ; we set down the 3qrs. under the 13 8 4 2 column of qrs. and carry the quotient (1d.) 130 18 3 3

to the column of pence, and the amount is

27d. which we divide by 12, the number of pence in a shilling, and the quotient is 2s. and the remainder 3d. ; we place the remainder 3d. under the column of pence, and carry the quotient to the shillings, and the amount is 385. which divided by 20, gives the quotient £1, and the remainder 18s. which we place under the shillings, and carry the 1 to the pounds, and the amount is £130.
