Embedded calc mode is amazing, thanks for the link! It does not seem as intuitive to work with equations (I've tried doing the Functions and Solving Equations examples in calc), and there are funny results with spaces in names. If someone knows how to do the even/odd example in calc, please let me know. Here is what I got so far: * Variables #+BEGIN_SRC calc m := 42 b := 1000 m x + b => 42 x + 1000 mass of earth := 5.972e24 kg mass of moon := 7.34767309e22 kg mass of earth / (mass of moon) => earth / moon #+END_SRC * Functions #+BEGIN_SRC calc eq := f = 1.8 c + 32 ceq := solve(eq, c) => c = f / 1.8 - 17.7777777778 subst(eq, c, 20) => f = 68. subst(ceq, f, 100) => c = 37.7777777778 even(n) := n = 0 ? true : odd(n - 1) odd(n) := n = 1 ? true : even(n - 1) #+END_SRC Thanks again for pointing me to how great calc can be, Alan
