Some equations may require numbers to be entered in superscript or subscript form. e.g.
x³+2x²−5
To enter superscript numbers with the mouse select the number mode using the the ↑n and ↓n buttons. When one of these modes is active clicking the number buttons will enter numbers in superscript or subscript. To return to normal number mode click the active button.
To enter superscript numbers with the keyboard hold down Ctrl while entering the number. Hold Alt for subscript.
The number mode returns to normal when entering the next non-number character (e.g. +).
