Texas Instruments, the No. 1 recommended brand of graphing calculators in the U.S., has optimized its most powerful Computer Algebra System (CAS) math engine for an all-in-one iPad app that makes teaching and learning math more engaging, meaningful and … fun!


Open the door to math mastery with the first-in-class iPad CAS app that delivers comprehensive graphing, data entry and analysis, statistical modeling and calculating functionality.

Solve equations with algebraic precision, factor and expand variable expressions, complete the square, find antiderivatives, compute limits, find exact solutions in irrational form and more.

Make math more meaningful by importing images from the iPad camera or photo library and overlaying graphs and equations on them to illustrate abstract math principles in the real world.*

Visualize crucial connections by observing how equations change — in real time, on one screen — when you touch, grab and interact with shapes, graphs and objects on the screen.

Graph functions, inequalities, implicit functions, conic sections, scatter plots, statistical plots and regression models, 3D graphs, parametric, polar and differential equations.

Enter equations in proper math notation so math symbols and formulas on the screen are identical to those in text books and on the board.

Deepen understanding by exploring hundreds of free activities for Pre-Algebra, Algebra, Geometry, Calculus, Statistics, Pre-Calculus and more from the online Math Nspired resource center.

Create and store work on your iPad, and share it using your Email or Dropbox account.

The application does what it claims. I like the calculator, but I don’t see Texas Instruments improving the application to its best. Now the IPadOS 15 is here, and iPads themselves have been improved a lot, but this application remains static and rigid, resembling a previous standard…no updates in particular Texas Instrument should consider the fact that technology nowadays is conveying the idea of being more futuristic day by day. If smartphones and iPad are reaching more people, then iPad and smartphone versions of this application should should be offered more frequently. I would say, not leaving the hand held calculators, but definitely working more on this type of software.

Apple also does a terrible job approving apps lacking of some basic parameters…like an app should in principle cover or fit the size of the screen.

Difficile d’ouverture à partir de l’cran

L application ne s’ouvre pas correctement
Gros problème de fonctionnalité

Really useful for high school and undergraduate math, science and engineering

I absolutely love the idea of adapting the well-known Ti-Nspire CAS system for iOS. For those who know the world of computer-algebra systems Ti-Nspire is the small cousin of Mathematica or Maple systems, but imagine having a less powerful Mathematica on your Iphone, ready to be used when you’re idle on a bus. Better yet, you can really play with your hands and shift, zoom, drag graphs! You can’t really do that with Mathematica and that’s too bad. The calculator version was expensive and a pain in the neck, but now you have all the screen of your iPhone or iPad to play with. The cost ? Just don’t go to Starbucks for a week and that’s it, you paid it.
