Nowadays I'd probably just ask Claude to figure it out for me, but pre LLMs, WL was the highest value tool for thought in my toolbox.
(Edit: and they actually offer perpetual licenses!)
Mathematica seems a little pricey but maybe it would motivate me to learn more math.
I would love to read what non-mathematicians use MatLab, Mathematica, and Maple for.
(Mathematica is of course much better than Python at symbolic math, but this isn't what you are asking about)
