Good, but not so easy to make your own libraries without a lot of
programming knowledge (unless something changed since the last time I
looked at it).

The entire reason I wrote my equation manager.  It works, but is way
too big (32K?!?!), and way too slow (choose menus?!?!?).  Doesn't have
the ability for units in your calculations either. Until the latest is
up at hpcalc.org, you can get it here:

This lets you assign notes and units to variables in your equations,
as well as solve individual or multiple equations.
