TI-Nspire™ CX II CAS Graphing Calculator

Symbolic precision

with the advanced Computer Algebra System

The TI-Nspire™ CX II CAS graphing calculator offers advanced maths capabilities beyond the standard model — ideal for teachers and students to explore equations in symbolic form and to see both exact and approximate solutions.

Where to buy

Power up maths learning with CAS

Computer Algebra System (CAS)
Manipulate algebraic expressions, solve equations symbolically, and see exact solutions — no rounding, no estimates.

Responsive learning
Interact with maths, observe cause/effect, and see how it all connects.

Modern touchpad
Computer-like navigation with an on-screen cursor.

Save documents
Create, edit, save and review work just like on a computer.

Rechargeable battery
Stays powered between maths and science classes to exam day.

Approved for use

*With CAS disabled on the TI-Nspire™ CX II CAS graphing calculator.

Beyond numbers

The TI-Nspire™ CX II CAS graphing calculator handles all the numerical maths
the standard model can — plus symbolic maths and exact solutions for deeper exploration.

Powerful symbolic maths tools

Solve equations symbolically, manipulate algebraic expressions, factor polynomials, and perform symbolic integration and differentiation — all while keeping answers in their exact form.

Exact maths. Every time.

With the CAS model, fractions as fractions, radicals as radicals, and answers in symbolic form. Connect exact solutions with decimal approximations, making advanced maths more accessible and easier to understand.

Grasp the maths

Show students how changing one thing changes everything. They can explore and visualise connections between their graphs and the equations simultaneously in real time — no switching back and forth between screens.

Save your work. Review it anytime.

Distraction-free learning

Your maths class deserves better than a web browser

The TI-Nspire™ CX II CAS graphing calculator unplugs students from the web and social media, so teachers can keep them focused on maths.

The power of Python built right in

The TI-Nspire™ CX II CAS graphing calculator supports Python programming, allowing students to write and run code directly on the calculator.

Students are empowered to learn programming while exploring its wide range of applications in maths, science, computer science, and even data analysis — providing them a head start in coding as well as computational problem-solving.
