This is a Texas Instruments TI-84 Plus graphing calculator. It is fully compatible with the TI-83 Plus model, offering an easy transition for users. The calculator features an eight-line display with 16 characters per line and adjustable contrast. It includes a USB port for connecting to computers or other compatible calculators to transfer data or software. The device has three times the memory and a 2.5 times faster CPU compared to its predecessor, the TI-83 Plus. It is approved for use on many standardized tests, including the PSAT, SAT, and ACT. The screen is scratched with words big daddy. But calculator works.
