Solution 34876: Unable to Delete the Finance Application on the TI-84 Plus C Silver Edition Graphing Calculator.
Why am I unable to delete the Finance Application that is on the TI-84 Plus C Silver Edition?
Finance functionality is in the Apps list even though this is not an App. This happened when the product shifted from the TI-83 to the TI-83 Plus Family and TI-84 Plus Family.
A key on the keyboard needed to be freed to be able to add the [APPS] key. Matrix functionality was moved to the [2ND] [X-1] location, and a blue [APPS] key replaced the TI-83 [MATRIX] key. The Finance functionality is part of the OS and is not able to be deleted.
Please see the TI-84 Plus C Silver Edition guidebook for additional information.
