SIMPLE ?.^ULTIPLICATI0N, 21 



Use of the Table in MULTIPLICATION, 



Find die multiplier in the left-hand column, and the 

 multiplicand in the uppermost line ; and the product is 

 in the common angle of meeting, or against the multiplier, 

 and under the multiplicand. 



Use of the Table h DiFlSION'. 



Find the divisor in the left-hand column, and the div^i^ 

 dend in the same line ; then the quotient will be ever the 

 dividend, at the top of the column. 



R U L E.* 



I. Place the multiplier under the multiplicand, so that 

 units may stand under units, tens under tens^ &c. and draw 

 a line under them,

* Demon, i. When the multiplier is a single digit, it is plain 

 that we find the product ; for by multiplying every figure, that Is, 

 €very part of the multiplicand, we multiply the whole ; and 

 writing dov/n the proid-ucts that are less than ten, or the excess of 

 tens, in the places of the iigures multiplied, and carrying the num- 

 ber of tens to the product of the next place, is only gathering to- 

 gether the similar parts of the respective products, and is, there- 

 fore, the same thing, in effect, as though we wrote down the 

 multiplicand as often as the rriultiplier expresses, and added them 

 together : for the sum of every column ia the product of the 

 ^gures in t|ie place of that column ; and these products, collect- 

 ed together, are evidently equal to the whole required product. 



2. If the multiplier is a number made up of more than one 

 digit. After we have Ifound the product of the multiplicand by 

 the first figure of the multiplier, as above, we suppose the multi- 

 plier divided into parts, and find, after the same manner, the })ro- 

 duct of the multiplicand by the second figure of the multiplier ; 

 but as the figure we are multiplying by stands in the place of".
