each of the sums, and the lower less than the upper, subtract the lower from the upper, and set down the difference. If there is a fraction in the lower sum, and none in the upper, subtract it from 4, and set down the difference in this case there must be 1 added to the right hand figure of the cents, in the lower sum, before it is subtracted from the one above it. If there is a fraction in each of the sums, and the lower greater than the upper, subtract the lower from 4, add the difference to the upper, and set down the amount, In this case, as in the last, there must be one added to the right hand figure of the lower cents.

Proof; as in Simple Subtraction.

MULTIPLICATION OF FEDERAL MONEY.

:

RULE.

Set the multiplier under the sum to be multiplied: then, if there is no fraction, proceed as in Simple Multiplication observing to separate the cents from the dollars in the product. If there is a fraction in the sum, multiply it, and find how many cents are contained in its product: then multiply the cents of the sum, and add to their product the cents contained in the product of the fraction, and proceed as before directed. Or, if the multiplier exceed 12, multiply the sum, omitting the fraction: then multiply the fraction, and add the number of cents contained in its product to the product of the rest of the sum.

Proof: as in Simple Multiplication.

Note. To multiply a fraction of a cent, and find how many cents are contained in its product-multiply the upper number of the fraction, and divide its pro duct by the under one, and the result will be the number of cents.

DIVISION OF FEDERAL MONEY.

RULE.

Divide as in Simple Division. When a remainder occurs, multiply it by 4, and add the number of fourths that are in the fraction of the sum (if any) to its product divide this product by the divisor, and its quotient will be fourths; which annex to the quotient of

the sum.
