Designed to support high school students from 10th to 12th grade, across all tracks, the Casio Graph 35+E II Python is a graphing calculator powered by batteries—included from the start. Its 8-line × 21-character screen offers appreciable readability for following calculations and plotting curves, while its 60 KB user memory allows for storing programs and data without daily constraints. The high calculation speed streamlines intensive work sessions, and the icon-based menu makes navigation intuitive, even when deeply focused. The included 3-pin cable facilitates data exchange between calculators. A 3-year warranty (parts, labor, and return shipping) covers the investment throughout the entire high school curriculum.
