Does anyone know of a good adding machine app for the Droid? I realize there is the calculator app built in and multiple other scientific calc's out there. I'm looking for the basic functions of an adding machine.
For instance, I'm a contractor and need the ability to do the following w/o constantly re-entering the the value of the previous equation.
I always need to take the cost of the product, add tax and then add labor. I hate having to do "100 * .08" and then get the answer "8", write it down, and then have to add "100 + 8" and so on and so forth to get my total bill.
With my adding machine in my office, I can do the following keystrokes and get what I need:
"100 * .08 +"
This will take "100" and multiply it by ".08" and then add (+) it to the original value giving me a total of 108. Any ideas? TIA
