I'm new to TeX and I would like to use it to write math (on a Mac). I've just downloaded MacTex and I'm wondering what's the recommended workflow. Am I supposed to write math in TeX macros/code and perhaps get used and "see" through the TeX macros? Or should I use a wysiwyg editor ?
I'm also wondering how mathematicians do math on a computer even if they have no intention to publish their work.
