The TI-Nspire CAS handheld and software incorporates CAS (Computer Algebra System) as a tool for students to explore, evaluate, and simplify expressions, numeric problems, and variables in symbolic form. In most other respects the two units function identically and can be used side-by-side in the classroom.

Here are a few examples of functionality with CAS handhelds and software:

• Solve 5x + 2y = 10 for y [Answer: y = -(5/2)x + 5]
• Find the derivative of ln x [Answer: 1/x]
• Factor x^2 – 9 [Answer: (x + 3)(x – 3)]
