Sit back and relax because mathematical expressions are finally easy to write within text documents. MiKTeX is an up-to-date implementation of TeX and related programs for the Windows operating system.
TeX is a typesetting system written by Donald E. Knuth, who says that it is "intended for the creation of beautiful books - and especially for books that contain a lot of mathematics".
This program will enable you to save time and energy when writing intricate formulas.

Do you use LaTeX? I do. But I use it everywhere: Windows, Mac, UNIX, whatever. Under Windows, I've found MiKTeX to be a outstanding software that has very simple installation (well, as far as TeX installations go), easy updating and patching, outstanding performance, and I've never had a problem adding my own style files or templates.

MiKTeX Features:
* Easy to install
* Complete: 1600 packages (fonts, macros, ...) are included
* Living: packages are updated regularly
* Easy package management: missing packages can be installed automatically; a wizard helps you to keep your MiKTeX system up-to-date
* Fast previewing: the TeX output viewer Yap allows for an optimized edit-compile-view cycle (if the TeX authoring system in use supports source specials)
