As the title states, I am starting a pursuit of a B.sc. degree in mathematics next year.
What calculator does MHF recommend (let's pretend I'm rich)?
My favorite calculator is the TI-Nspire CX CAS calculator. It has EVERYTHING you could possibly want. You can check out it's features on the official site. Usually math classes tell you which calculator they prefer, so contact your instructor before you buy a calculator.
