FAQs

Q1. What is the difference between 'Adding Machine: 10 Key Calc' and 'Accountant Calculator' in the App. Store.?
A1. Both are single-column adding devices and both have iPad versions with full size 1:1 keyboards. '10 Key' behaves the same as a 10 Key Adding Machine with reversed operator entry while ‘Accountant Calculator’ supports the free chaining of +, -, x, /, %, √, 1/x and is easier to use if you are not familiar with how a '10-key' works.

A4. Touch any line of the paper tape to go into edit mode. Touch the side controls: Add Line, Delete Line. You can also edit numbers. Press Done to return to Calculator mode.

Q5. How can I have my 'total' key be on the right side?
A5. Press the checkerboard icon on the left side of the paper tape until the keypad you want is displayed. There are three to choose from.

Q6. Tell me about Email, Printing, and Exporting a Paper Tape.
A6. From the Export dialog, select from: Email, Print, Copy or Open-In. Email includes a pdf attachment. Print requires an AirPrint capable printer. Open-In will cause a menu of 3rd party Apps to appear that can receive a hardcopy of your paper tape; for example, iBooks, DropBox, and 3rd party printer Apps for Brother, HP, Epson, Canon and more. With these print directly to a network reachable printer (even if it is NOT AirPrint capable).
