The Texas Instruments TI-Nspire CAS with Touchpad is one of two graphing calculators (TI-Nspire / TI-Nspire CAS) released commercially in early 2010 as upgrades from the TI-Nspire and TI-Nspire with Clickpad (2008). In particular, the model hosts a new touchpad positioned beneath the display that allows for trackpad-like input and clickpad-like clicking. Like its immediate peer (the TI-Nspire CAS), the CAS w/Touchpad stores and displays values symbolically instead of as floating-point numbers. Plus it includes algebraic functions and calculus functions, making it an optimal choice for university students. Additional features include easier access to files and tools, a scratchpad functionality for performing quick calculations without opening a file, and compatibility with wireless student response/classroom polling systems.

Additional Information

The Texas Instruments TI-Nspire CAS with Touchpad lacks a testing mode LED indicator, meaning it cannot be used in the ACT or IB. It is however okay for SAT and AP exams.
