**Function and Applications**

The TI-Nspire™ CX II-T CAS (Computer Algebra System) handheld device and companion software are designed to generate opportunities for classroom exploration and symbolic manipulations. In addition to the flexibility offered by the TI-Nspire™ CX CAS handheld device's simple, menu-driven document structure, the TI-Nspire™ CX CAS handheld device is enhanced by a backlit colour screen with the ability to import images and overlay graphs and other elements, bringing concepts to life. In addition can be used to program the TI-Innovator™ System.
