Before Buying Your TI84 Program Two Dimensional Figures (AREA2D), Download TI Connect CE

Download TI Connect CE first (Instructions here). You can download TI Connect CE for free here. Make sure you choose the right version for your desktop or laptop. There is one for Mac and two for Windows. You’ll want to choose a laptop or desktop that has a USB port. That way you can physically connect your TI 84 calculator to your computer so they can communicate.

You might have to use a non-Chromebook as some students said their school-distributed Chromebooks wouldn’t allow them to download TI Connect CE.

Once you’ve downloaded TI Connect CE, just link your TI 84 calculator with your USB to mini-USB cable. After your computer recognizes your calculator, you’re good to go. Then you can order AREA2D from this page.
