How to Reset a Casio FX-991EX Calculator

[@Okay250]

What do you press if you want to remove any numbers stored in the calculator for example the number "29" being stored as "A" but don't want to affect any other settings or wipe any other parts of memory?

Press the SHIFT button. Press the CLR button (it’s usually labeled as AC on some models). Select Memory (you may need to navigate using the arrow keys to find this option). Choose the memory location you want to clear (e.g., A, B, etc.). Confirm the action.
