For math.stackexchange.com which uses MathJax, I use MacDown, a markdown editor with parallel windows, one showing the MathJax and the other (in real time) the rendered math. I find it essential.

I enter my math directly into the editor without writing anything on paper. Works for me. The ability to copy and paste is invaluable.

Clif bars recently went from 6 bars per box to 5. They write the 5 on the box as if it is something improved, not reduced.
