This calculator helps to make summing a large list of numbers easier to type in.

An important note to those that are not aware of "adding machine" calculators: they do not add/subtract numbers in the way that you may be used to. For instance, most calculators to subtract 5 from 10 would have you key in "10", "-", "5", "=". For this calculator and other adding machines, you instead key in "10, "+", "5", "-". Note that you follow each number with it's positive or negative sign, instead of thinking of the calculation as a formula.

Double-tap or long-press a tape entry to edit the value.

My wife Cassandra is an accountant who loves the 10-key style "adding-machine" calculator she uses at work. Unfortunately, she could not find one to download and use for Android. I developed this app to fill that need for her, and realized that some of you may also have this need. I hope this app finds you well!
