Solution 34571: Cannot Delete the Finance Application on the TI-83 Plus and TI-84 Plus Family of Graphing Calculators.
Why can't I delete the Finance Application that is on the TI-83 Plus and TI-84 Plus family of graphing calculators?
Finance functionality is listed in the Apps menu. This happened when the product shifted from the TI-83 to the TI-83 Plus.
A key on the keyboard needed to be freed to be able to add the [Apps] key. Matrix functionality was moved to the 2nd function of [x^-1] key, and the Apps key replaced the TI-83 Matrix key. The Finance functionality is part of the OS and cannot be deleted.
Please see the TI-83 Plus and TI-84 Plus family guidebooks for additional information.
