MiKTeX

This program will allow you to easily create documents and books, as well as write mathematical or other scientific formulas. A traditional word processor doesn't have many features related to chemistry, math, or other sciences. These are usually resolved by various third party add-ons or similar software. This utility specializes in creating documentation for mathematics and other sciences. The app has a well-designed interface that makes it easy to use if you're already familiar with how LaTeX works. This program gives you all the tools you need to create documents efficiently and accurately, from simple things like changing letters to uppercase or lowercase to changing custom content. It is available for several platforms and you can work with many types of TeX files. MiKTeX is licensed as free software for PC or laptop with 32-bit and 64-bit Windows operating system. It is located in the Other Tools category and is available as a free download for all software users.
