Download MathTYpe 6.6 Regitered Version

MathType is a graphical editor for mathematical equations, allowing entry with the mouse or keyboard in a full graphical WYSIWYG environment This contrasts to document markup languages such as LaTeX where equations are entered as markup in a text editor and then processed into a typeset document as a separate step.
MathType also supports the math markup languages TeX, LaTeX and MathML. LaTeX can be entered directly into MathType, and MathType equations in Microsoft Word can be converted to and from LaTeX MathType supports copying to and pasting from any of these markup languages.
Additionally, on Windows 7 and later, equations may be drawn using a touch screen or pen (or mouse) via the math input panel.
By default, MathType equations are typeset in Times New Roman, with Symbol used for symbols and Greek. Equations may also be typeset in Euclid, a modern font like Computer Modern used in TeX, and this is included with the software. Roman characters (i.e. variable names and functions) may be typeset in any font.
