MULTIPLICATION OF DECIMALS.
/"rJTE down the factors, and multiply exactly as in
placing,jthe decimal point in the product, so as to
ke just as many decimals in it as there are in both facT
s ; and if there be not as many figures in the product as
re ought to be decimals, prefix ciphers to supply the
n't.
.Examples.
1. What is the product of *417 and 520-3?
2. What is the product of 91-73 and -381 ?
i. What is the product of -217 and -0431 ?
k What is die product of 5T6 and 21 ?
5. What is the product of 314 and *029 ?
i. What is the product of -051 and -091 ?
Contractions.
. When decimals are to be multiplied by 1 ucith any num-
of ciphers ; it is done by only removing, the decimal point
nany places farther to the right-hand as there are ciphers
he multiplier, and subjoining ciphers if need be-.
Examples,
. The product of 51-3 and 1000 is 51300o
J. The product of 2-714 and 100 is
