Write an arithmetic expression in the top field,
e.g.: 2*3
and press Return (Enter) or click the
button: .

If you undo an entry, press Backspace or click the
button: .

Both decimal point and decimal comma can be used.
if you use decimal point, do not type comma, and if
you use decimal comma, do not type period.

You can store numeric values ​​in letters.
Write for example: a=2 and later write 3a
and you will get the result 6.

Functions can also be used.
Write for example: f(x)=3x ,
and the function can be used.

Any angles must be stated in degrees.


The following writing methods are used
(almost as in Excel):
Write  Explanation
 Times
*
 e.g.: 7*3     instead of 7·3
 Division
/
 e.g.: 1/2      instead of ½
 Raising power:
^
 e.g.: 5^2     instead of 5²
  _
√
 Square Root
√
root(;
Sqrt(
^(1/2)
^0.5
  _
√9 can for example be written:
root(;9)  ( with semicolon   ; )
Sqrt(9),
9^(1/2) or 9^0.5

The √ key   can also be used
    _
 ª√
 a´th root
ª√
root(

^(1/n)
 fx:  root(3;27) ( with semicolon   ; )
or 27^(1/3)
i instead of ³√27

The key ª√   can also be used
 π
π
PI()
 e.g.: 2*PI()*5 = 2·π·5
  e  
 (Euler's
 number, approx.2.7)
e
e()
 e.g.: 2 *e()*5 = 2·e·5
 Log
 Common logarithm
 (base 10)
Log
Log10
 e.g.: Log(10) = Log10(10) = 1
 Natural exp function
exp
exp
 e.g.: exp(1) = exp(1) = e
and exp(2 ) = exp(2) = e()^2 = e²
 Ln  Natural logarithm
Ln
 e.g.: Ln(exp(7)) = 7
 Sin-1
 Converted to Sine
Sin-1
ArcSin
Sin^-1
e.g.: ArcSin(1/2) = Sin^-1(1/2) = 30°

Angles are in degrees
 Cos-1
 Inverse of Cosine
Cos-1
ArcCos
Cos^-1
e.g.: ArcCos(1/2) = Cos^-1(1/2) = 60°

Angles are in degrees
 Tan-1
 Inverse of Tangent
Tan-1
ArcTan
Tan^-1
e.g.: ArcTan(1) = Tan^-1(1) = 45°

Angles are in degrees
 !   Faculty
!
 e.g.: 3! = 1·2·3 = 6
 |   Numeric value
|
 eg: |-6| = 3
 f(x)=
 Definition of function
f(x)=
g(x)=
 e.g.: f(x)=5x or g(x)=2x-3
and then can be written for example: g(5)+2,
which becomes equal to 2·5- 3+2 = 9
 a=
 b=
 Assignment of value.  
a=
b=
 e.g.: a=7 and
later can be written e.g.: 5a +2,
which becomes equal to 5·7+2 = 37
