What is LaTeX?

LaTeX (LATEX, transliteration "LaTehe") is a typesetting system based on TEX . It was developed by American computer scientist Leslie Lamport in the early 1980s. Using this format, even Users without knowledge of typesetting and programming can give full play to the powerful functions provided by TeX , and can generate many book-quality printed materials within days or even hours. This is especially true for generating complex tables and mathematical formulas . Therefore, it is very suitable for generating high-quality technical and mathematical documents. This system is also suitable for generating all other kinds of documents, from simple letters to complete books. [1]

The formula in Word2019 will be directly converted into the following LaTeX code:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}
