whole multiplication. This may be all very 
true: the method of multiplying, of carry- 
ing one to the next figure, of arranging the 
feveral rows inclining gradually to the left 
may be rational, but the reafon is not 
very apparent. Let us try to explain the 
operation and demonftrate the truth of the 
refult. 
I am to multiply 425 
by '2 1 3 
Firft, I fay, 3 times 5 make ; 15 
Secondly, 3 times 20 make . 60 
thirdly , 3 times 400 make . 1200 
I now begin to work with the figure 
i : remembering it is a ten, 
I fay, ten times 5 make . 50 
Then, ten times 20 make . . 200 
And ten times 400 make . . 4000 
I now multiply with the figure 2, re- 
membering that it is 200: thus 
200 times 5 make . . 1000 
Secondly, 200 times 20 make . 4000 
Laftly, 200 times 400 make . 80000 
Now thefe added together make . 90525 
as before: fo that the ufual concife method 
of Multiplication is demonftrably true. 
From the foregoing example it is impof-
