not sorry for title but I long for the olden days when i could call and someone knowledgable would answer the phone - 

but i have a new hp50g -

upgraded from my 15c (if this tells you how old I am - good for you) - 

how the "F" do i change the sign value on a number...?

I am in RPN mode bc I know this and love it and will not change

Key the number, then press the [+/-] key, which is the key above the 7 key.  This is pretty much the same as the way you would use the CHS key on the HP-15C.  They just changed that key's name on the 50g to [+/-].

 

Note: In programs, however, that command will either appear as NEG (when by itself) or as a negative sign (when combined with a number).  For example, the following HP 50g RPN-mode program returns the number 3:

 

<< -3 NEG >>

 

Disclaimer: I don't work for HP. I'm just another old RPN addict. 🙂
