Calculation Priority Sequence
The calculator performs calculations according to a
calculation priority sequence.
• Basically, calculations are performed from left to right.
• Expressions within parentheses have the highest priority.
• The following shows the priority sequence for each
individual command.
1. Function with parentheses:
Pol(, Rec(
sin(, cos(, tan(, sin
–1
(, cos
–1
(, tan
–1
(, sinh(, cosh(, tanh(,
sinh
–1
(, cosh
–1
(, tanh
–1
(
log(, ln(,
e
^(, 10^(,

(,

2. Functions preceded by values, powers, power roots:

Percent: %
3. Prefix symbol: (–) (negative sign)
4. Statistical estimated value calculation:

6. Multiplication and division:

, variables (2

etc.), functions with parentheses (2

(3), Asin(30), etc.)
7. Addition and subtraction: +, –
If a calculation contains a negative value, you may need
to enclose the negative value in parentheses. If you want
to square the value –2, for example, you need to input:
(–2)
2
. This is because
x
2
is a function preceded by a value
(Priority 2, above), whose priority is greater than the
negative sign, which is a prefix symbol (Priority 3).
