In the late 70's I was taking an electrical engineering course under the G.I. Bill. I had just bought a TI pocket calculator with built in functions. We were doing meshes and nodes and the instructor informed the class that those calculators were nice, and use them if you wish, but if we followed his procedure they wouldn't be needed at all. Same thing in the tech math class which opened with a review of quadratic equations. Pi r square no pi r round cornbread r square.
