On a somewhat related note, does anyone have any particularly nice ways of writing math-related notes?<p>Part of me wants to just hand-write them and then maybe scan them, but that&#x27;s not searchable&#x2F;indexable, and doesn&#x27;t lend itself well to version control.<p>Writing in TeX or LaTeX would make them searchable&#x2F;indexable, but this seems a little heavyweight for just notes (like answers to exercises).  I don&#x27;t use TeX&#x2F;LaTeX that often, so I feel like I&#x27;d be spending half of my mental energy figuring out how to format things, figuring out how to invoke the tools, what packages to install, etc.<p>Are there any nice solutions out there for this sort of thing?
