Section 9.

COMPOUND ADDITION.

COMPOUND ADDITION is the adding together of two or more numbers of different denominations.

1. Paid a London tailor £7. 13s. 6d. 2qr. for a coat, £2. 17s. 9d. 1qr. for a vest, £3. 8s. 3d. 3qr. for pantaloons, and £9. 11s. 8d. 3qr. for a surtout; what was the amount of the bill?

Ans. £23. 11s. 4d. 1qr.

The sum of the farthings in the right hand column is 9 farthings, equal to 2d. 1qr.; we write the farthings under the column farthings, and carry the 2d. to the column of pence, the sum of which is 28d. equal to 2s. 4d.; we write the

4d. under its proper column, and add the 2s. to the column of shillings, the sum of which is 71s. equal to £3. 11s.; having written the 11s., we add the £3 to its column, and find the sum of which to be £23. From the above process, we induce the following

RULE.

Write all the given numbers of the same denomination under each other; then add the numbers of the lowest denomination together, and divide their sum by so many as make one of the next higher denomination; set the remainder under its column, and add the quotient to the next column; which add together and divide as before; thus proceed to the last denomination, under which place its whole sum.
