Great Start
I had the same problem with the 1,2,3, E -6, but 1,2,3, +,+ did give me 6 as expected.
RPN Calc
Published by: James Mattis
Description
A simple reverse polish notation calculator loosely based on my trusty HP-32SII that runs on iPhone, iPad, and Apple Watch!
If you are familiar with HP RPN calculators, the operation of this calculator should seem very straightforward - albeit simplified. It can't be programmed, and it doesn't handle binary, or hexadecimal numbers.
But, it has a clean, simple interface with large, easy to press buttons. It has all of the functions required for quick calculations when your iPhone is handier than your computer or calculator.
And, remember those cool calculator watches from the 1980s? Unfortunately, none of them were RPN. RPN Calc brings a reverse polish notation watch calculator to the Apple Watch!
In addition to the standard RPN Calculator app that runs on iPhone, iPad, and Apple Watch, RPN Calc includes a handy micro RPN Calc Today Extension available for convenient access to quick calculations from the pull down Today screen.

RPN Calc Reviews
Unable to enter a number. Unable to add up.
I have tried all the of ways I can think of to enter the number 123E-6 without success. The obvious key sequence of 1, 2, 3, E, 6, plusMinus leads to -123E6. The less obvious 1, 2, 3, E, -, 6 leads to nothing useful. Also the calculator does actually seem to work. Starting from a clear calculator, enter 1, 2, 3, +, + I would have thought that the answer would be 6. It's actually given as 7. This would imply that the calculator only have X and Y registers: no Z!
