BASIC
KEYS
AND
FUNCTIONS
Memory
Keys
There
are
8
muljti-purpose
memories
available
for
you
to
use
in
your
calculator.
These
memories
are
special
locations
in
the
machine
where
you
can
store
numbers
you
may
need
to
use
later
on.
The
memories
are
a
real
bonus
—
and
in
many
ways
give
you
“'several
calculators”
in
one,
since
you
can
store,
recall
or
perform
arithmetic
on
the
numbers
in
the
memories
without
affecting
calculations
you
have
in
progress
in
the
“main
machine”,
The
[6]
and
(A)
keys
will
not
affect
what's
in
the
memories
—
but
you
can
use
the
[INV]
[2nd]
I
key
Sequence
to
clear
them
all
out
if
you
need
to.
(Turning
the
calculator
OFF
and
ON
does
this,
too.)
Since
you
have
8
memories
you
need
to
tell
the
machine
which
one
you
want
to
work
with
at
any
given
time.
Every
time
you
push
a
memory
key
you
need
to
follow
it
immediately
with
the
number
of
the
memory
you
are
using
(n=
0,
1,
2/3,
4,
5,6,
or
7).
This
tells
the
machine
which
one
of
the
8
memories
you're
referring
to
at
the
moment.
The
operations
of
the
memory
keys
is
pretty
much
“common
sense"
as
shown
below.
[STO]
n
—
Tue
Store
Key
This
key
just
“stores”
the
displayed
number
in
the
memory
you
specify
with
n.
(n=0,1,2,...7).
(Any
number
previously
stored
in
memory
n
is
automatically
cleared
out
first.)
n
—
Tue
Recat
Key
Any
time
you
press
[RéiJn,
the
number
stored
in
memory
n
appears
in
the
display
and
can
be
used
in
operations
and
calculations.
The
number
remains
in
the
memory
after
you
press
[R@)n,
and
you
can
recall
the
value
from
any
memory
as
many
times
as
you
need
to
in
any
calculation.
A
stored
number
remains
in
memory
until
you
alter
it
with
another
memory
operation,
the
[INV)
(2na)
[iy
clearing
operation,
or
by
turning
the
calculator
off.
