'''LaTeX''' is a [[computer language|computer typesetting language]] for [[mathematical]] [[markup]]. It was designed and developed by Leslie Lamport<ref>Gratzer, G. ''First Steps in LaTeX''. Birkhauser, Boston; p. xiv (1999) [http://books.google.com/books?id=mLdg5ZdDKToC&lpg=PP1&pg=PR14#v=onepage&q&f=false]</ref> as an extension of TeX, an existing typesetting language developed by [[Donald Knuth]]. LaTeX is used nearly universally by [[mathematician]]s, [[physicist]]s, [[engineer]]s, [[computer scientist]]s and other scientists in need of technical [[formatting]] in their publications.

\documentclass{12pt}[article] %Specifies the font size and the document style
\documentclass{12pt}[article] %Specifies the font size and the document style

<math>\sqrt{\frac{1}{4}} = \frac{1}{2}</math>
Highly complex mathematical expressions are also possible; :
\operatorname{erfc}(x) =
\frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
\frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
would output:
<math>
\operatorname{erfc}(x) =
\frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
\frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
</math>
The style declaration, beginning and closing end tags are omitted for brevity.
