Note:
When
squaring
a
negative
value
(such
as
—2),
the
value
being
squared
must
be
enclosed
in
parentheses

Since

than

would
result
in
the
squaring
of

and
then
appending
a
negative

to
the
result.
Always
keep
the
priority
sequence
in
mind,
and
enclose
negative
values
in
parentheses
when
required.

Certain
types
of
expressions
can
cause
the
height
of
a
calculation
formula
to
be
greater
than
one
display
line.
The
maximum
allowable
height
of
a
calculation
formula
is
two
display
screens
(31
dots
x
2).
Further
input
will
become
impossible
if
the
height
of
the
calculation
you
are
inputting
exceeds
the
allowable
limit.
*
Nesting
of
functions
and
parentheses
is
allowed.
Further
input
will
become
impossible
if
you
nest
too
many
functions
and/or
parentheses.
If
this
happens,
divide
the
calculation
into
multiple
parts
and
calculate
each
part
separately.
Note:
When
you
press
()
and
obtain
a
calculation
result
using
Natural
Display,
part
of
the
expression
you
input
may
be
cut
off.
If
you
need
to
view
the
entire
input
expression
again,
press
and
then
use
@
and
®
to
scroll
the
input
expression.
Using
Values
and
Expressions
as
Arguments
(Natural
Display
only)
A
value
or
an
expression
that
you
have
already
input
can
be
used
as
the
argument
of
a
function.
After
you
have
input
S:
for
example,
you
can
make
it
the
argument
of
v_,
resulting
in
