About Adding Machine 10Key Univ Lite
'Adding Machine 10Key Univ Lite' behaves like a true '10 Key' or 'adding machine' like those made by Monroe, Casio, Sharp and others. Press asterisk (*) for a total, operator entry is reversed, and calculate percentages by multiplying and adding to a stream of numbers. SEE THE 1ST FAQ BELOW.
This universal version works with both iPhone and iPad. The iPad version features a full sized (1:1) keypad with TypeTone, a unique audio aid to help guide your finger back to the center of a key. The total (*) key (iPad or iPhone) can be on either the left or right side (Sharp or Canon style).
Also. Review & edit numbers, add or delete lines. Save & retrieve paper tape files. Export paper tape files to iBooks©, Dropbox©, or your favorite printing utility (see the FAQs).

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. The iPad version comes as close to touch-typing as a touch-screen can be. With ‘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,
