DescriptionAs per B36: please UNINSTALL the existing app before installing B36 or higher. I had to change the app ID which means if you upgrade it won't overwrite but you'll end up with TWO calculators.

RPN really shines when it comes to more complex calculations where operator precedence comes into play and brackets would need to be used. This is because an RPN calculator has a 4 level 'stack'./ K2 T% n9 i+ L1 |: b2 G# }5 z
