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

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, as shillings into pounds, hours into days, &c. This is performed 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. Change the order of the question, and divide your last product by the last multiplier, and so on.
