Reduction is either Descending or Ascending. Descending is when great names are brought into small, as pounds into shillings, days into hours, &c.-This is done by Multiplication. Ascending is when small names are brought into great, a shillings into pounds, hours into days, &c. This is erformed by Division. REDUCTION DESCENDING. RULE. Multiply the highest denomination given, by so many of the next less as make one of that greater, and thus continue till you have brought it down as low as your question requires. PROOF.

EXAMPLES IN REDUCTION OF FEDERAL MONEY. 1. Reduce 2745 dollars into cents. 100 Ans. 274500 Here I multiply by 100, the cents in a dollar; but dollars are readily brought into cents by annexing two ciphers, and into mills by annexing three ciphers. Also, any sum in Federal money may be written down as a whole number and expressed in its lowest denomination; for, when dollars and cents are joined together as a whole number, whout a separatrix, they will show how many cents the gen sum contains; and when dollars, cents, and mills are so joined together, they will show the whole number of mills in the given sum.-Hence, properly speaking, there is no reduction of this money; for cents are readily turned into dollars by cutting off the two right hand figures, and mins by pointing off three figures with a dot; the figures to the left hand of the dot, are dollars; and the figures cut off are cents, or cents and mills.
