Texas Instruments TI Programmable 57 User Manual

A TOUR OF
KEYS AND FUNCTIONS
Your
calculator
is
a
powerful
problem-solving
device
that's
especially
designed
for
easy
use.
You've
already
seen
some
simple
programs
in
action,
and
we'll
continue
to
discuss
the
programming
side
of
your
calculator's
capability
in
later
chapters.
But
apart
from
its
programmability
—
your
calculator
is
a
versatile
and
powerlul
“slide
rule’
calculator.
It's
always
ready
to
handle
calculations
right
from
the
keyboard.
In
this
chapter
we'll
be
touring
the
direct
problem-solving
keys
on
your
machine
—
the
keys
you
can
use
immediately
to
get
answers.
Then,
in
later
chapters,
we'll
show
you
how
these
basic
keys
can
be
used
with
the
others
on
the
keyboard
to
create
programs.
The
keyboard
of
your
calculator
has
been
organized
and
arranged
in
a
common
sense,
straightforward
way.
You
can
easily
do
simple
things
like
balancing
your
checkbook
or
adding
your
grocery
bill,
as
well
as
complex
technical
problems
-
The
usefulness
of
any
machine
or
tool,
however,
depends
on
the
person
who
operates
it.
You'll
want
to
get
familiar
with
all
of
its
features
—
all
of
what
it
will
(and
will
not)
do
for
you.
To
get
full
use
from
your
calculator,
take
the
few
minutes
necessary
just
to
see
each
key
in
action!
To
make
it
easy
for
you
to
get
acquainted,
this
tour
is
divided
into
three
major
sections:
Basic Keys and Functions
Advanced/'‘'Slide
Rule"
Keys
&
Functions
Statistical Functions & Keys
For
those
of
you
who
have
already
owned
or
are
familiar
with
an
advanced
slide
rule
calculator
—
you
may
want
to
skip
to
Chapter
3
and
get
right
into
programming.
If
there
are
some
keys
on
the
machine
you
don't
know
about,
however,
we'd
advise
that
you
take
this
quick
tour.
Take
out
your
calculator
and
keep
it
handy
as
we
go
through
the
keys
—
relax
—
and
let's
go.
