Word does its own mathematical typesetting with a GUI, but it also lets you use some LaTeX-like formatting if you want. 5\cdot2=10 will give you exactly what you typed, but if you hit space after the cdot, you'll get the centered dot symbol. Notably, it uses parens instead of braces, so you'll want to do \sqrt(2x+1). Most annoyingly to me, \frac and other commands not directly associated with a symbol do not seem to be supported. That said, it's still extremely useful for my narrow use case (high school teacher semifluent in TeX with colleagues who are not). edit: Also, it supports more symbols than its GUI provides; the only way to get the arc symbol that Geometry teachers like is to use \overparen.
