If you are new to the TI-Nspire graphing calculator, and you are enrolled in the second semester algebra course, this app is for you. The app includes 24 short video clips that will cover key topics in the first semester of algebra. At the end of each video clip is a Summary of the Keystrokes. Also, as a quick refresher of the TI-Nspire graphing calculator, from the main menu the Summary of Keystrokes can be accessed for any video clip without watching the video.
