One of the greatest motivating forces for Donald Knuth when he began developing the original TeX system was to create something that allowed simple construction of mathematical formulae, while looking professional when printed. The fact that he succeeded was most probably why TeX (and later on, LaTeX) became so popular within the scientific community. Typesetting mathematics is one of LaTeX's greatest strengths. It is also a large topic due to the existence of so much mathematical notation.
This is by no means meant to be a tutorial to teach the basics of LaTeX. This was prepared to serve as a reference once you've learned the basics. My suggestion would be that, you should learn LaTeX from the official documentation or wikibook or any other course/source that suits you the most.
