Classic Scientific 30
Classic Scientific 30 is a two-line scientific calculator: you type a whole expression on the top line and press enter to see the answer on the line below. It shows fractions, roots and powers the way you write them on paper, keeps a history of earlier lines, and adds a data editor with statistics and a function table. This manual covers every key, menu and mode, with worked examples you can follow key by key.
Designed to feel familiar if you have used a TI-30XS MultiView scientific calculator.
