FEDERAL MONEY. 10 mills (m.) make 1 cent marked c. 1 dime d. 10 dimes 1 dollar dol. or $. 10 dollars 1 eagle E. 8. In 3 dimes how many cents ? 9. In 5 dollars how many dimes ? How many cents ? 10.

It is usual to write dollars and cents in the following manner : 43 dols. 5. d. 7 c. and 4 mills, is written $43.574. The character $ written before shows that it is federal money. The figures at the left of the point (.) are so many dollars, the first figure at the right of the point is so many dimes, the next so many cents, and the third so many mills. It may be observed that when dollars stand alone, they are changed to dimes by annexing one zero to the right, because that multiplies them by 10. They are changed to cents by annexing two zeros, because that multiplies them by 100. They are changed to mills by annexing three zeros, because that multiplies them by 1,000. Thus 43 dollars are 430 dimes, 4,300 cents, or 43,000 mills. 5 dimes are 50 cents, or 500 mills. 7 cents are 70 mills. The above example then may be read 43 dols. 57 cents and 4 mills; or 435 dimes, 7 cents, and 4 mills; or 4,357 cents and 4 mills; or 43,574 mills. When there are dollars, dimes, and cents, the figures on the left of the point may be read dollars, and those on the right, cents; or they may be all read together' as cents. When the number of cents exceeds 100, they are changed to dollars by putting a point between the second and third figures from the right. If there are mills in the number, all the figures may be read together as mills. Any number of mills are changed to dollars by putting a point between the third and fourth figure from the right; the figures at the left will be dollars, and those at the right, dimes, cents, and mills. Since any sum which has cents or mills in it, may be considered as so many cents or mills, it is evident that any operation, as addition, multiplication, &c. may be performed upon it in the same manner as upon simple numbers. If the sum consists of dollars and a number of cents less than ten, there must be a zero between the dollars and the cents in the place of dimese Thus 7 dols. and 5 cents must be written $7.05. 19.
