The modus opcrandl in Multiplication is as 
follows. 
Multiply 425 
by . 213 
In the above" example, beginning with 
the firft figure on the right hand, I fay, in 
the common language of the fchool, 3 times 
5 is 15, put down 5 and carry i; 3 times 
2 is 6, and i that I brought is 7; 3 times 4 
is J2, put down 12. I then take the fecond 
figure, from the right, of the multiplier , and 
with it multiply all the figures of the mul- 
tiplicand as before, putting down the pro- 
duel in a fecond line taking care to place 
the firft figure under the fecond figure of 
the firft line. I then proceed in the fame 
manner with the third figure of the multi- 
plier, placing the firft figure of the refult 
under the third of the firft product; as you 
fee in the example. The feparate refults of 
thefe three multiplications being thus ar- 
ranged beneath each other, I add them to- 
gether and the fum is the product of the 
whole
