LaTeX/TeX is a mark-up language that produces attractive text. LaTeX typesets a text file with commands tha describe how the text should be formatted. Like other languages, it is best learned by looking at examples.
The advantages of LaTeX include that it is public domain, platform and printer independent, allows mathematical symbols and equations to be entered much easier and quicker than word processors, and produces camera ready text. Its disadvantage is that it is not as easy to learn initially as a word processor.
Another reason for using LaTeX is that markup languages are becoming more important. But the most important reason is that after you learn LaTeX, you can focus on your writing and become more productive.
