TI-84 Functionality

Built-in interactive "Grab-and-Move" interface the TI-Nspire lets students observe relationships & the impact of changes to related equations & data. Explore on one screen up to four representations of a single problem, including algebraic, graphical, geometric, numeric & written. Calculator application lets students enter & view expressions, equations & formulas exactly as they appear in math textbooks. Graph equations, expressions & other functions, then watch in real time how changes to variables impact data. Using the interchangable TI-84 Plus keypad (included at not extra cost with the TI-Nspire) your eductaional handheld calculator can grow with into college-level math courses and beyond into the professional world!
The power of visualization – multiplied on a single screen.

With TI-Nspire™ and TI-Nspire CAS technology, educators and students can see multiple representations of a problem – algebraic, graphical, geometric, numeric and written – on a single screen. Explore individual representations, one at a time, or as many as four all on the same screen.

Choose different split-screen options. Using a drop-down menu, select the number of representations and their arrangement on screen.
Representations can be dynamically linked. This means that changes made to one representation of a problem are automatically reflected in other representations of the same problem – instantly, in real time, on the same screen. The dynamic linking of multiple representations provides real-time, interactive feedback so students can explore different problem-solving techniques.
