Multiplying…
The general format for multiplying is as
follows…
 (N x 10x)(M x 10y) = (N)(M) x 10x+y
 First multiply the N and M numbers
together and express an answer.
 Secondly multiply the exponential parts
together by adding the exponents
together.


Finally multiply the two results for the
final answer.

(2.41 x 104)(3.09 x 102)
– 2.41 x 3.09 = 7.45
–4+2=6
–7.45 x 106

Dividing…
The general format for dividing is as
follows…
 (N x 10x)/(M x 10y) = (N/M) x 10x-y
 First divide the N number by the M
number and express as an answer.
 Secondly divide the exponential parts
by subtracting the exponent from the
exponent in the upper number.



Finally multiply the two results together
to get the final answer.
(4.89 x 107)/(2.74 x 104)
 4.89 / 2.74 = 1.78
7–4=3

 1.78
x 103
