I managed to get through almost all my undergrad without a graphing calculator and just the basic scientific ones. Then my orbital mechanics class my senior year started requiring multiplication of 3 3x3 rotation matrices for coordinate transformations. It wasn't hard math but just so time consuming to do on tests. And then my composites classes required 6x6 matrices for stress-strain conversions. Not hard math but a pain in the rear end to do on a test when the professor writes the exam thinking everyone is going to be using a graphing calculator that you can just plug 9 numbers into some open & closed brackets and push enter. The box method is cool to do in your head and I think alot of people just intuitively do it as a way of rounding to make numbers easier to work with. The lattice method is neat but I would hate to be forced to do it in order to receive credit for a correct answer. It seems like the biggest problem with common core principles isn't that the method is wrong or bad, just different, but that you HAVE to do it that way or you don't get credit.
