The $\text{\LaTeX}$ typesetting system (typically pronounced "lay-tex", but also sometimes "lay-tek", "lah-tek", or "lah-tex") is widely used to produce well-formatted mathematical and scientific writing. $\text{\LaTeX}$ is very handy for writing equations such as

\[\sqrt[3]{4^2+\frac{5}{3}+\pi} \approx 2.75\].

Nearly every serious student of maths or science will use $\text{\LaTeX}$ frequently. Through these websites, you will learn what you'll need to express maths and science like a professional, much, much better than Microsoft Word!
