It stands for Computer Algebra System, see here: https://en.wikipedia.org/wiki/Computer_algebra_system. Although it includes many(!) capabilities beyond a traditional calculator, the key conceptual difference is a CAS manipulates variables symbolically rather than numerically. Experts will no doubt add additional clarifications below. CAS does not mean Algebraic Notation or Operations (i.e. non-RPN or non-RPL) as you were thinking, a CAS can be added to any type of system, though being symbolic, most equations are obviously expressed in algebraic format. --Bob Prosperi |
