Is this is a web based application of a desktop app.
Do you need to use the power button in this manner. What happens when you "power" off the calculator.

Typically you would set the application to 0 on load and then overwrite the value when you click a new digit, then subsequent digits get appended.
To rest everything to 0 you would have a seperate button usually called "C" to clear the screen.

In either case I assume that you have an event handler handling you power button press event. It sounds to me like the initial calculator value is not clearing so you need to implement that functionality. Maybe your saving it as a static variable.... not too sure without code.
