Casio’s FX-9750 GPlus Graphing Calculator is an unrelenting digital workhorse. Its 21-character, 8-line display provides a convenient backdrop for tables, graphs, and parametric functions. Suitable for working professionals and students, this calculator is accepted during state-level tests and assessments, including SAT and PT exams. Its icon-driven menu is easy to use and delivers quick access to its different functions. It can also be used to solve problems in courses such as biology, physics, chemistry, and finance.
Note: The text says it's a GPlus, but the picture is of a GII. I've sent a question in to find out which it is, but regardless, this is about half the price of these on Amazon. My kids seemed to go through calculators pretty quickly in high school and college, so I was always on the lookout for a good deal on these.
