LaTeX is a typesetting system commonly used for producing scientific and mathematical documents due to its powerful handling of formulas and bibliographies. It allows users to create high-quality documents with precise formatting, making it a popular choice among academics, researchers, and publishers. Unlike traditional word processors, LaTeX uses plain text files with markup commands to define the structure and layout of a document. This approach enables users to focus on content rather than formatting, resulting in consistent and professional-looking outputs, especially for complex documents that include equations and references.
