CASIO ClassPad II FX-CP400 CAS Graphing Calculator Black

The Casio ClassPad II FX-CP400 is a graphing calculator with Computer Algebra System (CAS) capabilities, allowing for both symbolic and numerical calculations. Users can solve equations, perform algebraic transformations, and generate 3D visualizations directly on the device. The calculator features a large, touch-sensitive LCD screen, which simplifies expression entry and graph interaction. It is primarily used for advanced mathematics in secondary and university education. Using symbolic notation, the device provides exact algebraic solutions rather than rounded decimal approximations.

The unit runs on four AAA alkaline batteries, with a manufacturer-rated lifespan of up to 100 hours depending on usage. A built-in backlight ensures the display remains readable in various lighting conditions. The physical layout includes a dedicated numeric keypad for data entry during financial or statistical work. Weighing 315 g and measuring 89 x 21.1 x 206 mm, the calculator is designed for portability. Data transfer is managed via a USB port for connection to a computer. An auto power-off function helps conserve battery life when the device is not in use. As this model does not include a protective cover, users should consider this when transporting the unit. Built-in tools for profit calculation are included to support financial and business tasks.
