Author:Hero van Jindelt
Description: Freeware: Print the text for pupils. Numerical 2D-calculator. We don't need words like imaginary, complex number, or Argand Diagram any more--save them for a history lesson. Ordinary vector-calculation with a "new" (centuries-old) multiplication, known to teachers already as multiplication of rotation-matrices. If you've always thought, "it must be like this," you can find an algebraic foundation in the "Manifesto di Bombelli."
