TeX

TeX is a sophisticated typesetting system created by Donald Knuth, primarily used for producing high-quality documents with complex mathematical formulas and precise formatting. It allows users to specify document structure and content using plain text commands, which TeX then processes to produce professionally formatted output, often in PDF or DVI formats. Trusted by academics and publishers, TeX ensures consistency and accuracy in documents requiring detailed formatting, especially for scientific and technical materials. Essentially, TeX automates the fine-tuned arrangement of text and symbols, providing control and elegance in document presentation.
