Accelerate the understanding process

The TI-Nspire™ CX graphing calculator’s innovative capabilities support teaching strategies that research has found accelerate understanding of complex mathematic and scientific concepts.

gen-product-icon-multiple-reps Multiple Representations of expressions in problems are presented simultaneously, enabling students to visualize how algebraic, graphical, geometric, numeric and written forms of those expressions relate to one another.
gen-product-icon-dynamiclinking Dynamic Linking across documents and multiple representations allows students to interact directly with the math by seeing how manipulating one form simultaneously changes all the others.

Make real-world connections

Import digital images — including your own photos — and overlay graphs and equations on them to see math and science at work in the physical world.*


Enter values in proper notation

Integrated mathematics templates permit students to enter expressions and see math symbols, formulas and stacked fractions just as they are printed in textbooks and on the board.

The unique Chem Box feature lets students easily input chemical formulas and equations.


Click, scroll, create and save like a computer

Use intuitive drop-down menus to navigate through the TI-Nspire™ CX graphing calculator.

Create documents and pages and save your work as simply as opening, editing and storing files on a computer.


Take it to the test

Standardized testing organizations have approved the TI-Nspire™ CX graphing calculator for SAT®, PSAT/NMSQT®, ACT®, AP® and IB® Diploma Programme high-stakes exams. It also is approved for some state exams.


Keep track of graphing calculators

Easily distinguish classroom handhelds from student-owned calculators with EZ-Spot loss prevention features. The “school bus yellow” back cover, and faceplate inscribed “SCHOOL PROPERTY” provide effective theft deterrence.


Recharge, don’t replace for years

The TI Rechargeable Battery conveniently recharges using a USB cable, wall charger or TI-Nspire™ Docking Station. The TI Rechargeable Battery reduces the risk of running out of power unexpectedly and eliminates the need for routine battery replacement. Under normal usage, the rechargeable lithium-ion battery should last for up to three years.
