The equation editor
FullProof's built-in equation editor is a virtual keyboard for writing algebraic expressions quickly and easily.
Opening the equation editor
The equation editor opens in two situations:
- Choosing an equation in the proof: New statement or equation, then an equation from the Equations topic or from the shortcuts at the top of the window.
- Writing a value under Value in the menu of a segment or an angle in the diagram.
