Line 3, the calculator
line,
is
used
for arithmetic calculations.
At
times,
the
calculator line is also
used
as
an
edit
line.
Information
you type is
displayed
on
the
calculator line,
where
it
can
be
edited. Then, de-
pending
on
the
type
of
calculation you
are
doing,
some
other
key
enters
that
information
into
the
HP-18C.
The contents
of
lines 1
and
2
depend
on
the
type
of
calculation you
are doing. Sometimes those lines display a history
of
the
previous
contents
of
the
calculator line. At
other
times, lines 1
and
2 display a
variety of
information,
such
as results
of
calculations, lists
of
num-
bers,
the
time
and
date,
and
instruction messages.
When
you
turn
the
HP-18C
on
for
the
first time,
numbers
are
dis-
played
with
two decimal places
and
with
a
period
as
the
decimal
point.
You
can
change
the
number
of
decimal places,
and
you
can
also
interchange the use
of
commas
and
periods
in
numbers
(for example,
change 1,000.00 to 1.000,00). Refer to pages 43
and
44 for
additional
information.

the
Keyboard
Figure 1-2 illustrates
the

keyboard
and
briefly describes
the
use
of
many
of
the
keys.
