Used graphing scientific calculators like the TI-73's TI-82's, TI-83's, and TI-84's can be purchased on-line for as little as $5. Cell phones calculators are not permitted for exams. If you plan to take college board exams, you must have a calculator that meets standards: If you want proof, see You are also required to bring a three ring binder with a dedicated science section and maintain a portfolio folder to remain in the classroom.
