  3. 1. Background

  4. 2. MathEdit Overview • MathEdit is an interactive visual mathematical expression editor. Running in a Web browser, it allows you to create and edit mathematical expressions with a convenient and intuitive graphical user interface. With MathEdit, users can easily enter mathematical expressions as answers to questions in mathematics lesson pages for example. Web page authors can also use MathEdit to create mathematical expressions to be included in their XHTML documents.

  6. Main Functionalities • Create a new or edit an existing mathematical expression interactively with a convenient GUI • Direct editing of MathML code • Set mathematical expression format and style • Customize toolbar, palette and expression template • Import/Export MathML • Capture and retrieve the MathML markup from other applications or webpage. • Open an existing MathML file stored in the local file system or at the originating Web server • Save MathML in a local or remote file • Return the result mathematical encoding (content, presentation, and composite) to the parent window

  10. Limit Template Fraction Template 4.1 Template

  11. 4.2 Sub-expression Navigation • MathEdit keeps track of the sub-expression and displays a color background to visually identify it to the user. • The arrow keys are used to move the current sub-expression • up to the parent node • down to the first child • left/right to sibling nodes.
