Mathpad is an easy to use text editor for mathematics. You can mix together ordinary text and any mathematical expression. Ideal for math teachers to create quizzes, tests and handouts. Also, you can save the formatted text as an image. With most equation editors you choose a template with the mouse, type a few keystrokes and repeat the process. Mathpad doesn't work this way. Mainly, you just type characers at the keyboard. Most people find this to be easier and faster.
Mathpad has some unusual features. For example, the implementation of standard italics for math symbols is simplified by the "automatic math" specification. In this mode, the ordinary text and math expressions get italicized correctly. Another example - the macros feature allows macros with arguments and is easier to use than more sophisticated macros as in Tex/
