Pre-Owned Texas Instruments TI-83 Plus Graphing Calculator, with Protective Cover, High School and College

The Texas Instruments TI-83 Plus handles algebra, geometry, trigonometry, statistics, pre-calculus, and financial mathematics, covering every standard math course in the middle school and high school curriculum. It is approved for the SAT, ACT, PSAT/NMSQT, AP, and IB exams. The large 64 x 96 pixel display renders 8 lines of text, equations, or graph data, with adjustable contrast for clear viewing in any classroom setting. Flash ROM technology with 160 KB of storage allows the operating system and applications to be updated, giving the calculator a longer useful life than fixed-firmware alternatives. Students can graph 10 functions, 6 parametric expressions, 6 polar expressions, and 3 recursive sequences at once, using 7 distinct graph styles and 14 zoom features to explore mathematical relationships. Statistical tools include 10 regression models, scatter plots, histograms, box-and-whisker plots, probability distributions, hypothesis tests, and confidence intervals. An interactive equation solver and alphabetical function catalog provide quick access to every capability. The calculator runs on four AAA batteries with a lithium backup for memory protection, and an impact-resistant slide case is included. For families looking for one calculator that will serve a student for years, this model covers the full standard curriculum.
