I’ve been slowly working my way through a math text for fun. (Hold all accusations of nerd-dom for the end, please.) So far I’ve been taking notes and writing up proofs and all that using a notebook and a pencil. I decided that typing would be much neater than my handwriting, but quickly discovered that getting OpenOffice to display the proper symbols was often difficult and convoluted. (The built-in equation editor worked fine for some things, but I couldn’t figure out how to show anything similar to, for example, the union symbol in this: Example )
Is there any relatively simple, cheap, good math writing software out there?
Note: I’m aware of LaTeX, but after dabbling with it very briefly some years back, I seem to recall it having quite the learning curve. Moreover, it’s definitely overkill for my purposes.
