### Description

How this app makes math so much easier:

• This manual shows all important functions of the new graphing calculator TI-Nspire CX (and CAS), which are very useful for high school and college. Actual calculator not included!

• The app shows the exact key press sequence for 28 topics of Differential Calculus, Solve Equations, Integral Calculus, Matrices and CAS Functions!

• You can swipe through screenshots of the original graphing calculator which show every step you have to do (220 screenshots in total)!

• Or you can watch short video tutorials to see what you have to do.

• Additionally there are helpful descriptions in the app which give some hints and further knowledge.

• More than 50 math problems with solutions to practice your skills!

Not yet convinced? Here's how you would benefit from this app:

• Every topic shows a detailed instruction through screenshots of the original graphing calculator TI-Nspire CX which show how to solve the math problem. You only have to swipe to get the next screenshot which looks similar with your calculator display!

• To ”become warm” you have the possibility to insert a sample function in your calculator which is used in the app. The app shows an example for every topic. After that, press the first key of the respective key press sequence on the graphing calculator. Then swipe once again to get the next screenshot. It will look like the display of your calculator. The app contains for each step a picture, so it's easier to solve your math problems and become a TI-Nspire CX professional.

• The app is also useful for preparing your examination, because you often don't remember all instructions of the calculator.

• Your teacher will be grateful as well, because he doesn't have to walk around the classroom until everyone's calculator shows the right solution. You only have to take a look at the app and know how to do!
