Example.

I desire to know how much 125 l. being forborn 6 year will be increa∣sed, according to the rate of 6 l. per cent. reckoning Interest upon Interest or Compound-Interest.

Extend the Compasses from 100 to 106; that extent being 6 times re∣peated from 125, shall reach to 177 l. the principal increased with the inte∣rest at the term of 6 years, at the rate propounded.

But if it were required for any number of Months, then first find what 100 is at one Month, then say thus, If 100 give 10 s. at one month, what shall 125 be at 6 months end? facit 75 s. And the work is thus:

First say, If 100 give 10 s. at one months end, What shall 125? and

it makes 12 s. 6 d. then say, If one month require 12 s. 6 d. What shall six months require? facit 75 s. that is three pound fifteen shillings, the thing required to be found.
