There being two decimals in the multipli- 
cand and one in the multiplier, I point off 
three decimals in the product. 
In the multiplication of Algebraic quan- 
tities, you have only to write the letters in. 
a line one after the other; to multiply the 
coefficients as in common Arithmetic, and, 
when the figns are fimilar, to prefix the 
fign +> when difiimilar , thus, 
Multiply a Multiply c Multiply d 
By b By d By + e 
Product ab -\-cd -de 
Multiply 1 2 x Multiply A: -f-jr

This, you will fay, is very eafy and per- 
fectly clear, as to the manner of working: but
