Place the moveable Multiplier inverted in fuch a 
manner, as that its laft Figure I may be juft over 5* 
the lall Figure of the Multiplicand. Multiply thefe to-, 
gether (Tx 5 = To 1 and fet down the laft Figure of 
the Produd: o juft under, referving the firft Figure T 
for the next place. Then move the Multiplier a place 
forwarder, fo that two of its laft Figures may be 
over two of the laft Figures or the Multiplicand, and 
then Multiplying and colleding you will have 
14-1x1+4x5 = 17. Set down 7 in the next place 
oi the Produd, and referve i. At the next remove 
you will have i4ix544xi+-4X5 = 3i. Set down 
I and carry 3. . Then 3 -f 1 x“i +- +-4x1 +• 4 x 5 
= 03 = J7. Set down 7 and carry 3. Then 7 + 2 x 
c> 44X.’ -1-4x34-4x144x5 = 3= 17. Set down 
7 and carry 7 . And fo proceed as long as there can 
be any Figures over one another, and the Produd will 
be found as before. 
This w'ay of Multiplication is fo eafy, and may be 
made fo familiar by a little Pradice ,* that it will be 
but little fliort of Multiplication hy Infpe^ion^ and will 
doubtlefs feem very furprizing to thole who are only 
acquainted with the common tedious way of Multipli- 
cation : efpecially if we content our felves with a men- 
tal preparation of the Numbers given, or only mark 
thole Figures that are to be changed, which by fome 
Pradice is eafily attained.
