Would really like something selfhosted that does the basic Wolfram Alpha math things.

Doesn't need the craziest math capability but standard symbolic math stuff like expression reduction, differentiation and integration of common equations, plotting, unit wrangling.

All with an easy to use text interface that doesn't require learning.

Try maxima, it's open source:

https://maxima.sourceforge.io/

I used it when it was called Macsyma running on TOPS-20 (and a PDP-10 / Decsystem-20).

Text interface will require a little learning, but not much.

Maxima is amazing and has a GUI. My only beef with it is it doesn't show its work step by step.

That's wolfram mathematica.

TI-89 has surprisingly good symbolics tools and solvers for something that runs all year on a single set of AAA batteries. Feels like magic alien tech.
