FAQ's
Q1. What is the difference between 'Adding Machine 10Key Univ', and 'Accountant Calc' in the App. Store.?
A1. Both calculators are single-column adding machines or calculators with full-size (1:1) keypads and are optimized for the iPad User Interface. '10 Key' behaves the same as a 10 Key Adding Machine with reversed operator entry while ‘Accountant Calc’ supports free chaining of +, -, x, /, %, √, 1/x. It is easier to use if you are not familiar with how a '10-key' works.
Q2. Can I touch-type?
A2. Only the iPad version includes ‘TypeTone’, a key will guide your finger back to the center of a key with an audio tone.
Q3. How can I edit an incorrect number or add & delete lines from the paper tape?
A3. Touch any line of the paper tape for edit mode. Touch the side controls: Add Line, Delete Line. You can also edit numbers, split Add/Sub or Mul/Div groups. Press Done to return to Calculator mode.
Q4. Tell me about Email, Printing, and Exporting a Paper Tape.
A4. Email includes a pdf attachment. Print requires an AirPrint capable printer. Open-In will cause a menu of 3rd party Apps to appear. Once exported, print directly to a network reachable printer (even if it is NOT AirPrint capable).
