The equations you have typed in are "equations" in the mathematical sense, not assignment statements. > Is it possible to work with the "$" unit? $ means something specific in calc (cannot remember what). I use "USD" instead, for instance, and it works fine. The following single line calc block does do what you want: #+begin_src calc solve([a = 300 m, b = 300 m, Area = a*b, cost = 1 (USD/m^2), z = Area*cost], [a, b, Area, cost, z]) #+end_src #+results: : [a = 300 m, b = 300 m, Area = 90000 m^2, cost = USD / m^2, z = 90000 USD] -- : Eric S Fraga, with org release_9.5.5-966-g88c85d in Emacs 29.0.50
