I feel like graphing calculators enable exploration in a way that doing it manually with pen and paper cannot. Obviously, pen and paper is super valuable as well, but I feel that they are complimentary.
All of that mostly comes up in physics and chemistry were its about knowing what long formulas you need to plug the numbers you have available to you to find out what you need to know. Oddly enough their seems to be very little benefit to using a graphing calculator in a actual math class.
I think I figured out what the B stands for, but where I'm from, we call it PEDMAS - the P standing for Parentheses.
For maths not so much, as it was less about providing a numerical answer, and more about understanding the question.

- graphing calculators were fine. Just don't make it too obvious you were playing Pokemon Red on it.
