Incremental operation shortcut

[biuklija]

A standard function of all calculators is performing "incremental" operations simply by entering the value, followed by the operator and the result button, i.e. entering [ 500 ], followed by [ + ], followed by [ = ] performs "500+500" and yields "1000". Further keypresses on [ = ] increase the result in increments of 500.

Simple Calculator requires one to enter 500 + 500 to achieve the same result. Would it be possible to implement the 'standard' behaviour?

Every physical digital calculator I have ever owned had this as standard. So does the windows calculator.
