Building on the hugely popular TI-83 Plus, which is perhaps the best-selling calculator of all time, the TI-84 Plus Silver Edition is completely compatible with the TI-83 family. This new model adds more speed (a processor that's 2.5 times faster), an enhanced high-contrast display (eight lines by 16 characters), changeable faceplates (silver included), and a suite of 30 Apps. And with nine times more memory than the TI-83 Plus (1.54 MB of RAM, 480 KB Flash ROM), there's plenty of room for even more Apps and your own data storage.

The calculator can compute real and complex numbers, calculated to a 14-digit accuracy, and displayed with ten digits plus a two-digit exponent. It can graph ten rectangular functions, six parametric expressions, six polar expressions, and three recursively-defined sequences. Up to ten graphing functions may be defined, saved, graphed, and analyzed at one time.

All this power is generated by only 4 AAA batteries with a lithium battery backup to protect RAM memory during main battery change. The calculator comes in an impact-resistant slide case.
