Another way to get out of RPN is to click on the top bar, View and uncheck the RPN option. It shows a key combo of CMD-R to toggle as well.

Hey Ashwin... My HP RPN got me thru all my electronic courses and helped me pass my FCC exams. LOL. But I agree, it is a rather backward way of doing math. :)

I also have a Dual Line display HP with RPN. It threw me for a loop at first but once I got used to it I loved it. My friend Matt gave it to me and it got him through all his engineering courses in Graduate school! I still have it and it still works great. It's an HP 42S RPN.

No, not at all. It's sooo logical. Loved it on my HP-41c calculator. I once found a program for the quadratic equation written in 15 or 16 steps. Without RPN, it could not have been done so efficiently.
