REDUCTION,

TEACHES to bring or change numbers from one name to another, without altering their value.

མ་

Reduction is either Descending or Ascending,

Descending, is when great names are brought into smali, as pounds into shillings, days into hours, &c.-This is done by Multiplication.

Ascending, is when small names are brought into great, is shillings into pounds, hours into days, &c. This is perormed by Division.

REDUCTION DESCENDING. RULE.-Multiply the highest denomination given by so many of dje next less as make one of that greater, and thus continue till you ave brought it down as low as your question requires.

1

PROOF. Change the order of the question, and divide your last oduct by the last multiplier, and so on.

Examples in Reduction of Federal Money.

1. Reduce 2745 dollars into cents.
2745 dollars
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, without a separatrix, they will show how many cents the given 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 mills 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 tents and mills.

Ans. 4878
