This app allows students and teachers to create interactive documents that combine text, mathematics, and images. Students can write out their problem‑solving process, insert a calculation from the Calculator app, paste a graph from the Graphs app, and then add commentary explaining the connections. This creates a complete portfolio of their work, which can be saved and transferred to a computer for grading. The Notes app supports rich text formatting and can include hyperlinks to other parts of the document.
While powerful, the CAS functionality makes this calculator restricted on some standardized tests:
The calculator solved it in 0.3 seconds. But Alex didn’t check the answer. Instead, he spent eight minutes doing the iteration by hand, filling three pages of notebook paper with trembling arithmetic, eventually arriving at y(0.5) ≈ 1.283. The calculator’s correct answer was 1.297. Alex, flushed with pride, wrote down 1.28. ti cx ii cas
To verify: If your device has a label reading or D-XXXXX and includes "CX II CAS," you own the 2019+ model. If it says "CX CAS" without "II," it's the original (2011-2018).

The hardware is built for the classroom. The included rechargeable battery is designed to last through a full week of classes and is charged via a standard USB port. The device also features a touchpad for computer-like navigation.
The TI felt something it had never been programmed to feel: a low, humming irritation. A feedback loop of despair. The Notes app supports rich text formatting and
The CAS engine allows the calculator to perform symbolic math. For example, if you input a variable expression, it won't force you to assign a number to that variable.
The handheld uses a document‑based operating system that allows for the creation, storage, and retrieval of work files. Files created on the handheld have the ".tns" extension and are fully compatible with the TI‑Nspire computer software. A user can start an assignment on the handheld in class, transfer it to a computer at home, and continue working on it using the larger screen and full keyboard of a PC or Mac. The file system supports folders for organizing work by subject or assignment.
