I’m thinking about concentrating in Applied Math or at least some concentration related to higher level math. I figure that a calculator is required (correct me if I’m wrong). Which type of calculator should I get? I’m currently using my high school’s TI-83. Should I get a TI-84? Or should I go with TI-89? I know the community college near my high school doesn’t allow students to use TI-89, but is it the same with Harvard? Or should I look at another brand altogether?
I want to get one before I leave the US for the entire summer.
Thanks in advance!
