Resetting a TI-84 graphing calculator can be necessary for a variety of reasons, such as when the calculator is experiencing errors, when it is not responding to input, or when the user wants to clear all of the data and settings from the calculator.
There are two main ways to reset a TI-84 graphing calculator: a soft reset and a hard reset. A soft reset will clear the calculator’s memory and restore it to its factory settings, while a hard reset will also clear the calculator’s flash memory, which is where programs, apps, and other data are stored.
