The HP 50g is a CAS graphing calculator with multiple formatting functions. It doesn't have a color display, but does have a large screen with adjustable contrast. There is plenty of storage for upgrades and applications, and it comes with an equation library. While it's useful for students and professionals, it is permitted for use on only a few standardized and AP tests.

There are more than 2,300 integrated functions in this graph calculator, including advanced functions like scatter plots, 3D graphing, angle conversions, hypothesis tests and symbolic differentiation. This makes it useful in high school and college courses in math, science, statistics and business. It's also a great tool for professional math-heavy jobs like engineering, surveying and computer science.

The system uses a Computer Algebra System (CAS) and features three input options: RPN, textbook data entry and algebraic formats. These functions limit its use on tests, however, since many testing services won't allow it. Students may use this graphing calculator only on the SAT Reasoning Test, SAT Math Level 1 and Level 2, and the PSAT/NMSQT.

The device features a large LCD adjustable-contrast display. It also offers plenty of storage with 2.5MB of total memory and an SD card slot that give you enough space for multiple applications, equation saves and future upgrades. A USB kit comes with the graph calculator, along with four AAA batteries. An auto-off feature saves battery power by shutting the device off after five minutes of non-use. It also features a slide case, but no color options.

While its use on tests is limited, the functions of this powerful device make the HP 50g a great graphing calculator option for both students and professionals. It offers a large storage capacity, multiple format options and a built-in equation library.
