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.

Excellent software

I purchased the very excellent Ti Nspire CX CAS a year ago. It is a super graphing calculator with plethora of functions useful up to and beyond university math. The calculator comes with a very good software application that mirrors all of the calculator's functions and allow for printing and saving. This tablet application is an exact replica of the PC software and gives the same functionality as the £ 150 calculator for just £ 20. I know it may look like an expensive app but trust me it is not once you realise it's full potential. A must for anyone serious about math.

Thank you for a great App

App withdrawn from UK App store - disappointed.
Programme developed a long time ago from a calculator base having limited memory, consequently it works
but the navigation is basic and the error messages are cryptic.
You will need help to use the App.
That said, it is a powerful tool. Just wish it was using more of the amazing capability of the ipad.

Very grateful for your offer concerning the calculator.
Worked out that the CAS is more powerful one, (but may not be allowed at school.
Having to help with the scientific homework, which I knew many years ago.
The app appears to be both useful, and powerful.
Many thanks, again.

Despite the high price tag, seeing the app was by Ti I got very excited. I was particularly looking forward to quality graphing capabilities. In short I'm disappointed, particularly with the 3D graphing as spherical and cylindrical expressions aren't allowed. In fact graphs can only be input in function form i.e. subject = expression. Graphing two equal expressions, often extremely convenient, isn't an option in this app. I was pleasantly surprised with the geometric construction facilities but that's not what I got the app for. Also the nifty ability to change 2D polynomials and trig functions by 'physically' manipulating their graphs while impressive isn't very useful for me and isn't applicable to polar expressions. To summarise this app is quantity over quality, clunky as opposed to slick and intuitive and does't really take full advantage of a tablets abilities. However there are lots of applications to utilise so three stars.
