2/ORDER
OF
OPERATIONS
AND
LEVELS
Operations are performed in the following order of
precedence:
1. Functions
2.
x",
xv,
ROP,
POR,
n
Pr,
nCr
3. xX, +
4.+,-
Operations
with
the
same
precedence
are
performed
from
left
to
right,
with
operations
enclosed
in
paren-
theses
performed
first.
If
parentheses
are
nested,
the
operations
enclosed
in
the
innermost
set
of
paren-
theses
are
performed
first.
*Registers
Li
through
Le
are
provided
to
store
opera-
tions
of
lower
precedence
(including
parenthetical
operations).
Since
six
registers
are
provided,
calcu-
lations
up
to
six
levels
can
be
retained.
*Since
each
level
can
contain
up
to
three
open
paren-
theses,
parantheses
can
be
nested
up
to
18
times.

3/CORRECTIONS
If
you
notice
you’ve
made
a
mistake
when
inputting
a number
(but you have not yet pressed
an arithmetic
operator
key), just press {@ to clear the last value and
then input it again.
In a series of calculations, you_can correct errors in
intermediate results by pressing {@ to clear the last cal-
culation performed. You can then continue with the
calculation.
If you want to change input of the @, &, €3. B.
a), or operator key, simply press the opera-
tor key you want to change to. In this case, the most
recently pressed key operation is used, but the opera-
tion retains the order of precedence of the original
operation you input.
