This Calculator app has more than 50 pages. Each page has a specific purpose. The two most important pages are (1) a smart adding machine and (2) a Calculator.

The adding machine has a visual 'tape' that can hold 40 items. The left side of the tape contains an amount and on it's right is it's count, usually 1. Any tape item can be edited.

The calculator follows the procedure of adding your known numeric values first, thus avoiding the use of parenthesis.

They are stored in a stack (like a stack of dishes where you place (Push) a dish on the top and remove it from the top (Pop)).

This app uses the term 'Pop' and 'Push' and is used to move data to and from a page.

This app provides the functionality of both the hand held HP Financial and HP Scientific calculators.

It can do a copy/paste with Windows. On your phone you need to install 'Windows Swift Key' from Google Play.With this feature you can import an Excel comma delimited list

Another useful feature provides the ability to assign a name to a numeric value(up to 26). It participates in Pop and Push.

There is a backup facility where your data can be saved in a file on your phone. Your data is saved until you delete it.

There are help pages but if you are not familiar with the requirements of a particular page - it is not a tutorial. Please read "Read me First"

Enjoy...

Note - this is an upgrade of the app: RPN Turbo Calc
