MathBrush

MathBrush [pdf] is a pen-based system for interactive mathematics. The system allows users to write mathematical expressions as they would using a pen and paper, and manipulate the expressions using computer algebra system operations that are invoked by pen-based interaction.

MathBrush has released an app for the iPad. Click here for the MathBrush app web site.
