the other line continually, and take the refult for a dividend. 4 . Multiply the remaining terms continually, and let the product of them be a divifor. 5 . The quotient of this divi- sion will be the term required.
By producing terms here, are meant, whatever neceffarily and jointly produce any effecT ; as the Caufe and the Time ;
length, breadth, and depth ; buyer and his money ; feller and
his goods j all neceflarily infeparable in producing their feve-
ral effects.
In a queftion where a term is underftood, and not exprefTed
that term may be exprefTed by unity.
Example. If 250/. ferve fix perfons for nine months; how
long will 1000/. ferve four perfons at the fame rate ?
Here the terms which exprefs the condition are.

Where Q_is put to reprefent the term required. Among the conditional terms, fix perfons and nine months are producing, and 250/. is produced : among their corre- fponding terms four perfons and Qjire producing, and 1000/. are produced.
But it being impoffible to multiply the producing terms in the fecond line, and the produced in the firft, becaufe Q_is unknown ; therefore multiply the producing terms of the firft Jine, by the produced in the fecond, and divide by the pro- dud of the reft.
