Most if not all high schools and colleges in the US required TI “graphing” calculators for algebra/trig on up. I don’t know if they still do. I never saw this HP28, sounds awesome!

I remember one of my math teachers claiming only TI showed up to the math text book meetings or something like that, so guess what calculator the book recommends...
