Solving Multi-Step Inequalities

Computer and SmartPhone Calculator Apps

"Free Graphing Calculator" by William Jockusch is available on both ITunes (Apple) and the Google Play store (Android.)  Put these on your phone as they will give us a consistent graphing calculator so we can help each other figure out how to do things on them.

Also for the Android, "Calculator ++" can be added and "Graphing Calculator by Mathlab" would be a worthwhile addition.



For a Windows computer, Microsoft's "Mathematics 4.0" is a very capable scientific calculator program should you not have a smartphone.

Desmos is another promising application which can run on Apple and Android devices...
