To enter numbers, coordinates or equations (4.2) you may use arithmetic expressions with parentheses. The following operations are available:
| operation | input |
| addition | + |
| subtraction | - |
| multiplication, scalar product | * or space |
| division | / |
| potentiation | ^ or 2, 3 |
| factorial | ! |
| Gamma Funktion | gamma( ) |
| parentheses | ( ) |
| x-coordinate | x( ) |
| y-coordinate | y( ) |
| absolute value | abs( ) |
| sign | sgn( ) |
| square root | sqrt( ) |
| exponential function | exp( ) |
| logarithm (natural) | log( ) |
| cosine | cos( ) |
| sine | sin( ) |
| tangent | tan( ) |
| arc cosine | acos( ) |
| arc sine | asin( ) |
| arc tangent | atan( ) |
| hyperbolic cosine | cosh( ) |
| hyperbolic sine | sinh( ) |
| hyperbolic tangent | tanh( ) |
| antihyperbolic cosine | acosh( ) |
| antihyperbolic sine | asinh( ) |
| antihyperbolic tangent | atanh( ) |
| greatest integer less than or equal | floor( ) |
| smallest integer greater than or equal | ceil( ) |
| Runden | round( ) |
For example, the midpoint M of two points A and B might be entered as M=(A+B)/2. The length of a vector v might be calculated using l=sqrt(v*v).
We see that you can do calculations with points and vectors as well in GeoGebra.
