Same. I was happy with `apt install calc` (I think nowadays called apcalc) for years because it does arbitrary precision and isn't as awkward as a python shell or so, but qalc is clearly a step up with support for units and solving
$ calc 2^x=4
x is undefined
$ qalc 2^x=4
((2^x) = 4) = (x = 2)
I used the above for determining after how many years a given inflation rate doubles a price (1.03^x=2)
I think my most recent real-world application for units calculation was about how much energy a device uses in kWh after a year, given that it draws 10W during office hours:
With zsh you can call it with the noglob builtin¹, that way it doesn't try to parse the bracketed section as a globbing pattern; if that works for you, then you can simply "alias qalc='noglob qalc'" for future use.

It even does time calculations: 13:37-08:00 tells you that you've been working for about 5.6 hours.I don't know why this isn't the universally used command-line calculator. I have it on my phone as well via a Debian subsystem and it's the best
