10Calc Business Calculator


10Calc is a professional printing calculator, designed for Windows 10 PCs, tablets and phones.
This app has all the accounting features you need to replace your old adding machine.
It’s actually much better, because you can save and reload tape files and search, print, or email them.
You can even correct tape errors, and insert or delete lines (try that on an adding machine!)
10Calc fully supports both touch and keyboard / keypad input, including hotkeys.
