Enter
the

carefully

Once
entered,
to
calculate
the
factorial
of
any
number
(positive
integer
less
than
70),
just
enter
it
and
press

Notice
that
this
last
calculation
keeps
your
calculator
busy
for
quite
some
time.
Remember
any
time
you
put
your
machine
into
a
loop
—
give
it
time
to
crank
out
the
result.
Some
loops
can
take
hours;—
even
days!
Note
also
that
this
program
will
give
you
an
incorrect
result
for
0|
If
you
enter
Vand
press
®)—
the
result
is
zero,
not
1
as
it
should
be.
You
might
want
to
develop
a
program
where
you
do
not
get
an
incorrect
result
for
0!.
As
we've
already
mentioned,
using
the
Bad)
Mlkey
sequence
will
come
in
handy
in
a
variety
ol
situations.
In
this
section
we've
introduced
a
few
of
its
most
straight-forward
uses.
In
later
sections
we'll
be
speaking
more
on
the
“ins
and
outs”
of
its
application.
Next Stop
Develop
a
program
that
displays
the
factorial
of
the
numbers
1,
2,3,
4,...
etc.
You'd
like
each
integer
displayed
for
two
pauses,
then
its
factorial
displayed
for
three.
