REMARKS
Answer
is
+.3
as shown in window. Log regis-
ter
is
cleared to
+1.
This is the
general
method
for solving such
a
problem.
Consider
it
as two
chain multiplication
problems.
First, find the
product
of the denominator and take its re-
ciprocal;
second, chain multiply the reciprocal
with
the
numerator
terms.
NOTE:
The
previous
method must
be
modified if the
numbers
are
very
large
or
very
small. In these cases, a
long chain multiplication
prob-
lem
should be broken down into several
smaller
problems.
Other-
wise,
a
loss
of
precision
or overflow
may result. This is especially
important in
a
program.
Consider the
calculation of
(2000
x 3000
x 100)
i
(4000
x 5000 x 100) as an example.
