To create numbers, coordinates, or equations using the Input Bar you may also use the following pre-defined functions and operations.
Note: The pre-defined functions need to be entered using parentheses. You must not put a space between the function name and the parentheses.

| Subtraction | - |
| Multiplication | * or Space key |
| Scalar product | * or Space key |
| Vector product | ⊗ |
| Division | / |
| Exponentiation | ^ or superscript (x^2 or x2)
|
| Factorial | ! |
| Parentheses | ( ) |
| x-coordinate | x( ) |
| y-coordinate | y( ) |
| Argument | arg() |
| Conjugate | conjugate() |
| Absolute value | abs( ) |
| Sign | sgn( ) |
| Square root | sqrt( ) |
