HP Prime Graphing Calculator Multi-Touch 3.5in Color Display

Our review of the HP Prime Graphing Calculator finds it best suited to high school and college students who need a fast, durable graphing tool with full symbolic manipulation. The single biggest reason to buy is its combination of a responsive 3.5in multi-touch color display and an integrated computer algebra system, which together make switching between symbolic, graphical, and numerical views quick and intuitive for homework, exams, and classroom demonstrations.

Key Features

• Advanced graphing and CAS: The built-in computer algebra system and dynamic geometry let users manipulate expressions, solve symbolically, and explore complex graphs without switching devices.
• 3.5in multi-touch color display: A high-resolution screen with pinch-to-zoom and finger-driven graph interaction makes tracing, zooming, and sketching functions straightforward.
• Exam approved: Approved for PSAT/NMSQT, SAT, selected AP and IB exams, so it can be used in many high-stakes testing situations where permitted.
• Wireless and app integration: Optional wireless kits and the HP Prime Mobile App let teachers poll students, share screens, and mirror full calculator functionality across devices.
• Expandable memory: With 256 MB of flash memory, it stores programs, images, and multiple exam configurations for classroom use and projects.

Who It's For

The HP Prime is aimed at students and instructors who need a full-featured calculator for algebra, calculus, statistics, and engineering courses; its CAS and touchscreen make it useful for visual learners and classroom demos. It is also appropriate for exam takers because it meets approval for PSAT/NMSQT, SAT, IB and certain AP exams.

Those who prefer a very simple button-only interface or who need a device with longer proven battery life under heavy daily use might look elsewhere; some users report mixed experiences with ease of use and occasional functional issues, so buyers who require absolute plug-and-play simplicity may prefer a more basic model.

Pros & Cons
