TeX is a typesetting system widely used for producing high-quality documents, especially in academia. It excels at formatting complex mathematical equations and scientific papers, making it a favorite among mathematicians, physicists, and computer scientists. With its plain text input, users can create beautifully structured documents that look professional and polished. One of the key features of TeX is its ability to separate content from formatting. This means that users can focus on writing their text without worrying about how it will look on the page. Additionally, LaTeX, a popular extension of TeX, provides even more tools and templates, simplifying the process for users.
