Ideal for middle school through college. What's in the Box: TI-84 Plus calculator, impact-resistant protective slide case, TI connectivity/USB cable, silver oxide battery, four AAA batteries, Guidebook and free software Apps, warranty information. TI- Rechargeable battery Building on the hugely popular TI-83 Plus, which is perhaps the best-selling calculator of all time, the TI-84 Plus is completely compatible with its predecessor. From that well-established platform, this new model adds more speed (a processor that's 2.5 times faster), more memory (24 KB RAM and 480 KB of Flash ROM), an enhanced high-contrast display (eight lines by 16 characters), and more beloved Apps. Includes a USB Port and cable. It also adds USB on-the-go technology (cable included) that can be used to share files with other calculators or to connect to PCs or optional presentation tools.Comes with 12 pre-loaded Apps and supports all TI-83 Apps. Twelve Apps are pre-loaded, including Cabri Jr., CBL/CBR, Conic Graphing, Inequality Graphing, Probability Simulations, Science Tools, StudyCards, TimeSpan, Topics in Algebra 1 Chapter 5, Topics in Algebra 1 Chapters 1-4, Transformation Graphing, and more. For students in math and sciences, the TI-84 Plus is a powerful, problem-solving tool with features for storing, graphing, and analyzing up to 10 functions. Plus, it displays graphs and evaluates tables on a split screen, allowing you to trace the graph and scroll through table values simultaneously.Split screen lets you view a graph and its equation at the same time. With the TI-84 Plus, you can view an equation, its graph, and the coordinates all at one time. Jump from point to point by entering a number. Several useful plot types are available, including scatter, box-and-whisker, XY-line, histogram, and normal probability plots. Advanced statistics and regression analysis, graphical analysis, and data analysis are readily accessed, along with features for calculus, engineering, financial, logarithm, trigonometry, and hyperbolic functions--all crucial tools for advanced analysis. With its clear display and fast processing, the calculator incorporates graphing tools for mathematics and science course work, including statistics and finance.The included normal slide case is great for desktop work. The TI-84 Plus is powered by four AAA alkaline batteries (not included) and one silver oxide battery (included) for backup, with an automatic shutoff to save energy. It also comes with a hard normal slide case and is supported by a one-year limited warranty.What's in the Box TI-84 Plus, normal slide case, TI connectivity cable/USB cable, silver oxide battery, TI Product CD-ROM with full reference Guidebook and free software Apps, warranty information; four AAA batteries not included, alkaline recommended Features: All-purpose graphing: pre-algebra, algebra 1, 2, geometry statistics, biology, physics, business and finance Preloaded apps, 480 KB ROM, 24 KB RAM Function visualization, 96 x 64 display resolution Proactive case and USB cable included Product Details: Brand: Texas Instruments Color: Black Calculator Type: Graphing Power Source: Battery Powered Screen Size: 2.75 Inches Product Dimensions: 10.75 x 7.55 x 1.9 inches Item Weight: 13.8 ounces Item model number: 84PL/CLM/1L1/B Batteries: 1 Lithium Metal batteries required.
