We had this in the early 1990's, it was called Mathematica [0]

This is pretty cool, I have a long running hobby project to make something similar in the terminal. https://github.com/ShaneMarusczak/rm-repl

I was using Apple Notes for some “math thinking” the other week. A killer feature for me would be an easy way to input various math Unicode characters (I was just copy and pasting them).

Pretty cool. It looks like it also uses local storage - so if you navigate away and come back (or just refresh the page) all of your expressions are still there. A lot of paid productivity apps that I use don't even manage that.

Pretty cool but handling large numbers is pretty limited: chokes on 171! Or 5^5^5.

If your in the Apple ecosystem, Soulver is a similar app to this that is really great.

I still like it better than the math built into notes for anything beyond basics.

Cool project. I wonder what benefits it has over using good old Desmos Calculator.
