TeX and LaTeX (often stylized as T e X, La T e X, and T e X & La T e X) are two of the most widely used typesetting software developed by computer scientist Donald Knuth in the late 1970s. TeX is used to generate documents such as books, articles and reports, while LaTeX is a markup language used to create and design documents. They are both popular among writers, publishers, and academics, and are used in commercial publishing, scientific and engineering journals, mathematics research, and software development.

TeX is a typesetting system that provides an organized, orderly approach to document preparation.
