Usually you type normally in GC. Sometimes, however, you want something special, such as a superscript (for exponents) or the symbol π. Table 3.4.1 lists ways to tell GC to do something special.
Table 3.4.1. Basic GC Commands
| TO GET... | TYPE... |
| Exponent | Shift-6 |
| Exit exponent or move on to next term | $\downarrow$ or $\rightarrow$ |
| Division | / |
| Multiplication | * |
| Parentheses ( ) | ( |
| π | pi |
| θ | theta |
| Select the next higher expression that contains the insertion point | $\uparrow$ |
| A split definition (a piecewise function) | Ctrl-Shift-A |
| New line | Ctrl-Enter |
Figure 3.4.1 illustrates typing mathematical statements in GC.
