51,786 | I got excited about Calc's power as an embedded mode. Define some variables in natural inline notation and then do operations on them.

I use embedded mode all the time and it's one of the most understated features of Emacs! | To expand on @éric's answer: you can avoid having to activate the formulas explicitly with `C-x * a` by including these lines:
