Reduction is either Descending of 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, as shillings into pounds, hours into days, &c. This is performed by Division. REDUCTION DESCENDING. RULE.

Reduce 2745 dollars into cent3. flere I multiply by 100, the 100 cents in a dollar; but dollars are readily brought into cents by anAns. 274500 nexing two cyphers, and into mills by annexing three cyphers. 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, without a separatrix, they will shew how many cents the given sum contains; and when dollars, cents, and mills are so joined together, they will shew the whole nuniber ou mills in the given sum.--Hence, properly speaking, there is no reduction of this monry; for cents are readily turned into dollars by cutting off the two right hand figures, and mills by pointing off three figures with a dot ; the figures to the left hand of the dot, ar? dollars ; and the figures cut of are cents, or cents and milis. 2.
