HP Prime Calculator

Don't know why this forum is so difficult to navigate and use, but I hope this finds it's way to the correct expert.  And why is there no "Calculators" board here?  Tablets is gone too ...

 

An archived post here  https://h30434.www3.hp.com/t5/Tablets-and-Mobile-Devices-Archive-Read-Only/HP-Prime-using-user-varia...

has solved my immediate problem, but I expect many more.  The HP Prime Users Manual has many examples, but they are all for Algebraic mode, not RPN.  There are enough subtle differences between the two modes that new RPN users cannot guess how to make any of the examples work.  Over they years Joe Horn has been trying to help, but IMO there needs to be a completely separate Users Manual _just_ for RPN.  RPN is dying because of this lack of support.
