How
to
Use
This Manual
We
know
that
somewhere
out
there we could find a few people
who
are delighted at
the
prospect
of
reading
an
instruction
manual
cover-
to-cover-tables,
footnotes,
and
all.
If
you are
about
to immerse
yourself
in
this manual, we wish you
happy
reading. We've worked
diligently to make it a quality work
of
non-fiction.
Chances are, though,
that
you are
one
of
the
vast majority
who
likes
to
learn
by
seeing
what
happens
when
you press keys. The
HP-18C
has
been
designed to
help
you
do
just that. We've designed
the
man-
ual
to
be
a
companion
to this
process-something
you
use
to
answer
particular questions
or
to guide you
through
a particular procedure.
If
you'll
be
using
the
manual
that
way, we
have
some suggestions to
help
you
learn
to use
the
HP
-18C as quickly as possible.
• Take
the
time to
read
chapter 1.
Chapter
1 gives you
an
overview
of
how
the
HP-18C
works,
and
introduces
terms
and
concepts
that
are
used
throughout
the
manual. After you've
read
chapter 1, you
will
be
ready
to
start
using all
of
the
calculator's features, reading
other
portions
of
the
manual
when
necessary.
• Match
the
problem
you
need
to solve
with
the
calculator's capabili-
ties. There are several
ways
to locate
information
about
the
HP-18C's
features:
the
table
of
contents,
the
subject index,
the
list
of examples,
and
the
menu
maps
in
appendix
E.
• Before doing
any
time-value-of-money problems or cash flow prob-
lems,
learn
how
the
calculator uses positive
and
negative
numbers
in
financial calculations. For this information, refer to pages 58
and
83.
