k 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^(,  (, 

3

 (

Abs(

Rnd(

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

x

2

,

3

!,  , r, 

g

, ^(, 

x

Percent: %

3. Prefix symbol: ( ) (negative sign)

4. Statistical estimated value calculation: 

m

n

, 

m

2

5. Permutations, combinations: 

n

P

r

,

C

r

6. Multiplication and division:  ,  

Multiplication where sign is omitted: Multiplication sign

omitted immediately before  , 

e

, variables (2 , 5A,  A,

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).
