tiplication is to be perform’d, and the feveral Pro* 
duds coileded, according to the Rules of Specious 
Multiplication, wherein like Signs will make 
and unlike Signs will make — ' in the Produd. This 
will always make the Produds deftroy one another, 
or at leaft will deprefs and keep them low, and the 
Figures themfelves being always frnall, the Refuk 
will be always fmall, and often but a Tingle Fi- 
gure, which is the great Compendium of this Me- 
thod. 
When an Approximation only is defir’d, or when 
the Produd is to be produced to a given Number of 
places, the Operation may be continued one place 
farther, in order to obtain To many Places true as 
are required. For feldom any Corredion extends 
beyond the place immediately aforegoing, and that is 
generally correded but by an unite, and very often 
needs no Corredion at all; which will be of no 
fmall convenience in the Multiplication of Decimal 
Fradions. 
In this Method we may (if w^e pleafe) begin the 
Procefs of Multiplication from the Ibweft places, or 
from the right hand, as is ufual in common Arithmetick, 
and then the Corredion may be carry’d on continually 
to the next place, and To the Produd may be always 
comprehended in one Line, without the ufe of any Su- 
perfluous Figures. Of this I lliall give an inflance in the 
foregoing Example.
