What's the fastest way to preview changes as I learn TeX?

I am new member on math.stackexchange.com and I am surprised that I can automatically see math formulas and symbols that I am writing there. When I am writing a long formula or an equation in a TeX editor (TeXMaker), it is difficult to understand some things. Is it possible to use this kind of preview in an editor, and not only on the website?
