MathType 6.0

A powerful interactive equation editor that lets you create mathematical notation for word processing (iWork ‘09, Microsoft Word), web pages, desktop publishing, presentations, and for TeX, LaTeX, and MathML documents.
MathType with iWork ‘09:
- MathType Equation command on the Insert menu: When MathType is installed, a MathType Equation command appears in the Insert menus of all iWork applications. This command inserts a new equation at the insertion point.
- Double-click to edit: If you later want to edit an existing equation, simply double-click on it and it will open in a MathType equation window. Make changes then close the window to update the document.
- Cut, copy, paste, and drag-and-drop: You can also copy equations from a MathType window into a document or vice-versa, using either clipboard cut, copy, and paste or with drag-and-drop using the mouse.
- Many more features.
