Texas Instruments TI-84 Plus Graphing Calculator

Building on the TI-83 Plus, the TI-84 Plus Graphing Calculator 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 (24KB RAM and 480KB of Flash ROM), an enhanced high-contrast display (8 lines by 16 characters), and more beloved apps.

The 13 pre-loaded apps include 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.

With USB on-the-go technology and included USB cord, you can share files with other calculators or to connect to PCs or optional presentation tools.
