8. There were forty-one men concerned in the payment of a sum of money, and each paid 3 dollars and 9 mills; how much was paid in all? Ans. $123 36 cts. 9 mills.

9. The number of inhabitants in the United States is five millions; now suppose each should pay the trifling sum of 5 cents a year, for the term of 12 years, towards a continental tax; how many dollars would be raised thereby? Ans. Three millions Dollars. 2. To Multiply the denominations of Sterling Money, Weights, Measures, &c.

RULE. Write down the Multiplicand, and place the quantity underneath the least denomination, for the Multiplier, and in multiply

ing by it, observe the same rules for carrying from one denomination to another, as in compound Addition.*

When the multiplier, that is, the quantity, is a composite number, and greater than 12, take any two such numbers as when multiplied together, will exactly produce the given quantity, and multiply first by one of those figures, and that product by the other; and the last product will be the answer.

3. When no two numbers multiplied together will exactly · make the multiplier, you must multiply by any two whose product will come the nearest; then multiply the upper line by what remained; which, added to the last product, gives the answer

4. To find the value of a hundred weight, by having the

price of one pound.

If the price be farthings, multiply 2s. 4d. by the farthings in the price of one lb.-Or, if the price be pence, multiply s. 4d. by the pence in the price of one lb. and in either. case the product will be the answer.
