Out of those, I recognize "mathematical equations" as something I've ever tried, regardless of which software I've been using, and LibreOffice Math always fit my needs. The truth is, outside of programming, I don't use enough of the features of office software for it to make a difference which suite I use.

I'm not sure what you're trying to prove. That there are features in some Windows software that aren't in Linux software? Granted, but I don't see how that's relevant to my original comment.
