# LaTeX

From Script | Spoken-Tutorial

**LaTeX** is a **typesetting software** for document preparation, letter writing, report writing and such. When writing, the writer uses plain text and LaTeX does all the formatting, stylizing and indentation. LaTeX's prominent use is in the preparation and publication of books and articles that contain complex mathematical formulae, numbering and cross-referencing of tables and figures, chapter and section headings, the inclusion of graphics, page layout, indexing and bibliographies.

**Learners** : UG/PG students, faculty and research scholars.
