From Ken Torimaru:
Adding Machine A simple adding machine with editing capabilities. Ideal for someone who needs to add a series of numbers. Enter your list of numbers, correct any errors, and it automatically update your result. Great for splitting a group lunch or dinner bill, tracking the cost of your items while shopping, or performing any basic math function (addition, subtraction, division, multiplication, percentages, etc.) Easy to use with same features and functionality as a traditional adding machine, including scrollable tape. 3 Views: Portrait Landscape with big keys and small tape view Landscape with large tape view The tape persist from view to view which allows you to enter numbers with the big keys and review and edit on the long tape.
