MathType is a powerful interactive tool for Windows and Macintosh that lets you create mathematical notation for word processing, web pages, desktop publishing, presentations, and for TeX, LaTeX, and MathML documents. MathType has hundreds more symbols and templates than Equation Editor. Beside our exclusive Euclid? math fonts, you can also make use of the 1000's of math symbols in fonts already on your computer, as well as math fonts you can download from the Internet. MathType's Insert Symbol dialog allows you to explore the available symbols and insert them with a click or keystroke. In addition to Microsoft Word and PowerPoint, use MathType to add equations to QuarkXPress and Adobe InDesign layouts, Excel spreadsheets, HTML pages, and many more applications and document types. Works with Wikipedia: Wikipedia, the popular online encyclopedia, contains 1000's of pages with mathematical equations. Once you do your research on Wikipedia, you can copy the relevant equations for use in your own work. You can also use MathType to author new equations for Wikipedia. MathType can add equations to virtually any application that has an Insert Object command or into which you can paste or drag a graphic. Equations can be created quickly by choosing templates from MathType's palettes and typing into their empty slots. MathType applies mathematical spacing rules automatically as you type. If you already know the TeX typesetting language, you can enter equations quickly using MathType's TeX input mode. TeX editing can be mixed with point-and-click editing so you get the best of both worlds. You can also paste in equations from existing TeX documents.
MathType takes full advantage of Office 2007's new Ribbon User Interface making it easier than ever to do equation operations in documents and presentations. New equation numbering and browse features work with all Word equation types. MathType adds a toolbar and menu to Microsoft Word and PowerPoint, allowing quick access to its features and powerful commands to do equation numbering, produce great-looking math web pages, presentations, and much more.
