MULTIPLICATION OF FEDERAL MONEY. RULE. Q. How do you place the numbers to be multiplied? A. In multiplying Federal Money, place the numbers according to their value; i. e. dollars under dollars, cents under cents, &c. and proceed exactly as in whole numbers. Q. Where do you place the separatrix in the product? A. Place the separatrix as many figures from the right hand, as there are figures at the right of the separatrix in both the factors; and if there be not so many decimal places in the product, supply the defect by prefixing cyphers at the left hand. Q. When there are more than three decimal figures, what do they signify? A. When there are more than three decimal fractions, all the figures to the right hand of mills, or the third place, are decimal parts of a mill. NOTE. Q. What do dollars multiplied by dollars, produce, &c. ? A. Dollars multiplied by dollars produce dollars; also, MULTIPLICATION OF FEDERAL MONEY. 71 dollars multiplied by dimes, produce dimes; dimes multiplied by dimes, produce tenths of dimes; dollars multiplied by cents, produce cents; dimes by cents, tenths of cents; cents by cents, hundredths of cents; dollars by mills, produce mills; dimes by mills, tenths of mills; cents by mills, hundredths of mills; mills by mills, thousandths of mills, &c.

To find the total product of the numbers here given to be multiplied, begin and multiply each figure in the multiplicand by the mills, or thousandths (1) in the multiplier, the product of which, set below the multiplier; then multiply each figure in the multiplicand by the cents, or hundredths (5) in the multiplier, the product of which, set below the first product; the tenths being a cypher, omit it, except bringing it down; then multiply each figure in the multiplicand by the dollars, or units (2) in the multiplier, the product of which, set below the second product; add the three products together, the amount of which, set underneath, and it will be the total product, or answer. To prove the work, first cast the nines out of the multiplicand, the remainder of which being 5, place at the right hand of the cross; then cast the nines out of the multiplier, the remainder of which being 8, place at the left hand of the cross; then cast the nines out of the total product, the remainder of which being 4, place below the cross; lastly, the product of the remainders of the multiplicand and multiplier being 40, cast out the nines, the remainder of which being 4, place above the cross, which (4) corresponding with the figure below the cross, proves the work to be correct. 2.
