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! ONE CAS APP. ALL THE MATH. 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. A COMPLETE LEARNING RESOURCE TI Education Technology is committed to success in mathematics by providing advanced learning tools that have been designed in collaboration with leading educators and researchers. TI provides world-class professional development for teachers, as well as free activities and curriculum content.

  • Great product

    By Jmitchell242
    This app helped me through college algebra, statistics, etc. it's now helping me with my daughters high school math. It's a little difficult at first. I've had to watch a number tutorials to master! Would give a five it was easier to navigate.
  • Where is the financial solver?

    By Grunkmump
    This is a great app but needs work. Where is the finance solver?
  • Love it

    By Tech Shop
    I love this app. The graphing capabilities allows my students to visual see the translations, and stretches.
  • Great version of the calculator, just missing iCloud Drive support

    By The real BigJim
    It would be a much better solution if it supported iCloud Drive in addition to DropBox as I will never use DropBox and iTunes sharing has been removed. Otherwise I am impressed with the provided functionality.
  • Doesn’t look like real Nspire

    By D_Snow
    This makes it nard to learn as the videos on the web are so different. Also it only works in when the ipad is held sideways, while the real calculator is held upright. Took 5 minutes to discover that one must click “New” to even see anything that looked like a calculator. So far I am sorry that I spent the $30.
  • Excellent, but...

    By Youitry
    I was unable to use this app at all until I, at last, located a downloadable manual. This, and an introductory tutorial, should be presented immediately to new users and kept highly visible on the main menu.
  • Perfect for tutoring

    By slsommers
    I use this app to support my tutoring students that have nSpire CX calculators. Sometimes they have trouble learning to zoom on their calculator & the iPad's pinch & drag mode makes resizing graphs much easier. Once they get it where they like how it looks, I have them copy the x-y settings so they learn more about their calculator. I just wish this had some more of the teacher features like the press-to-test mode so I didn't have to break out my real calculator to get them used to preparing for exams.
  • Doesn't fully support iOS

    By hilltrot
    This programs does not fully support iOS despite its significant cost. Hopefully, they change this in the future.
  • Great!!

    By Zach37473772
    Excellent app. I can use it when I can't find my regular calculator. Has all the functions I need. My only complaint, I wish that in the letters area, the y key could just be right there so I don't have to hold down on the x button, since I frequently use the y key for graphing.
  • Incredibly difficult to figure out

    By A n y M o u s e
    Not intuitive at all. Even after reading the 'manual' and multiple website help pages, I still can't figure this app out. I'm probably just too stupid to use it. The TI-83 and Voyage 200 both worked for me for years without any problems. I've written many programs over the years for both of those calculators, and also for the Mathematica and Maple Windows applications. So when I bought the TI-Nspire app, I was expecting either a graphing calculator app (like the TI-83 or Voyage 200) or a math program (like Mathematica or a Maple). Unfortunately this app is neither. In fact, I'm still not sure what this app is. :-(
