What Calculator do you guys currently use? I currently use a Hp 33S scientific calculator as well as a hp 50G graphing calculator. Thogh these calculayors are great, I am wondering if I should get rid of them or not use them alot, so I can get stronger math skills. I tend to be very reliant on my calculators. Also I have heard from other students that in higher math classes such as Differential equation sna d Multi variable calculus, that calculators arent allowed.
