To buy Zoom Math you need your calculator's zCode.
Zoom Math creates a unique code (the zCode) for each calculator. Your zCode will be twelve letters separated into three groups. Example: tpnv-ftby-ttth
If you have already loaded Zoom Math 100 or Zoom Math 200 onto your calculator, run the app, then press the ZOOM key to view the zCode.
Otherwise, follow these steps to get your zCode:
- Download the Zoom Math file to your computer for the app you want to buy.
- Install the app on the calculator via TI Connect.
- Get the zCode from the calculator by running the app and pressing the ZOOM key.
