How do I get the RPN mode to go away?

If you have the original one, you can't, RPN is it. The newer ones have a button to toggle between the 2 modes on the front of the calculator to the left of the "7" key. It is orange so you have to press the orange "f" key first.

Press f ALG to switch to the Algebraic mode.

ALG is the shifted function of the EEX key.

Your HP 12c Platinum is in Algebraic mode. To switch back to RPN mode, press f then CHS.

I take it you mean a 12C Platinum.

Press f ALG. ALG is the f-shifted function of the EEX key, just above the double-size ENTER key. This will switch the 12C Platinum from RPN mode to Algebraic mode, and ALG indicator will light up instead of the RPN indicator.

To switch back to RPN, press f RPN. RPN is the f-shifted function of the CHS key just above the EEX key.

I checked the manual, the image of the face of the calculator and **there is no way to change the entry mode from RPN to Algebraic**. Your calculator is still in RPN, it is the only mode it has. Reset it.
