REDUCTION. THE object of Reduction is to change the denomination of numbers without altering their value. It consists of two parts, Descending and Ascending. The former is performed by Multiplication, the latter by Division.

Reduction Descending teaches to bring numbers of a higher denomination to a lower; as, to bring pounds into shillings, or tons into hundred weights.

Reduction Ascending teaches to bring numbers of a lower denomination into a higher; as, to bring farthings into pence, or shillings into, pounds.

REDUCTION DESCENDING.

EXAMPLE. 1. In 48£. 12s. 7d. 2 qr., how many farthings?
