TI-Nspire CX II Graphing Calculator

This item is a Texas Instruments TI-Nspire CX II graphing calculator, readily identifiable by the 'TI-nspire CX II' and 'TEXAS INSTRUMENTS' branding prominently displayed above the screen. The calculator features a sleek design with a primary color scheme of white for the body and a vibrant blue for the side casing, with black accents for the keys and screen bezel. It has a large, full-color LCD screen, which shows some visible smudges and possibly a light film or dust, suggesting moderate use. Below the screen is a comprehensive keyboard layout, divided into several functional zones. There's a navigational touchpad-like area in white, surrounded by various function keys such as 'esc', 'save', 'tab', 'on', 'off', '+page', 'doc', and 'menu'. Further down, a standard numerical keypad with keys '0' through '9' is arranged in a typical calculator format, with additional arithmetic operators ('+', '-', '*', '/', 'enter') and mathematical functions ('= trig', 'ctrl', 'log', '10^x') on the sides. A full QWERTY keyboard is present at the very bottom, indicating advanced functionality for text input and programming. The keys are a mix of white (for the navigational keys) and black (for numeric and QWERTY keys), with white lettering. The overall condition appears used but functional, with no apparent major cracks or damage, although the screen could use cleaning. The light-colored casing might show minor scuffs or discoloration upon closer inspection, but none are clearly visible in the provided images. This model is commonly used in educational settings for algebra, calculus, and other advanced mathematics courses, reflecting its modern manufacturing and robust design.
