76. 1. Subtract $109.02 from $963.03.

OPERATION.

$963.030 109.025

For convenience, we write the subtrahend under the minuend, so that figures of the same order shall stand in the same column, and begin at the right to subtract, observing to place the decimal point between dollars and cents.

Here, in the subtrahend, we write the cent as

5 mills; and in the minuend note the place of mills by 0.

Dividing the dollars and the cents, we have a remainder, which we write as a part of a

cent.

In the second operation, the division is extended to mills by supplying the mills' place in the dividend. The two answers, although a little different in form, express the same value.

[blocks in formation]

not exact.

How may the division be extended from dollars to cents, when there is a remainder, and no cents in the dividend? Ans. By supplying the two places of cents by ciphers. How may the division be extended to mills from cents, when there is a remainder, and no mills in the dividend? Ans. By supplying the place of mills by a cipher.
