On: Soulver – Notepad, meet calculator

Not sure why I got downvoted here, so I'll explain that Mathematica makes a really good proxy for this.

I can do a decent amount of this in Notebooks or the terminal with Wolframscript and I'm not limited to simple things either.

I'm sure this tool is better if you just need something really simple as it is much cheaper and certainly lighter weight than Mathematica.
