Is that like this:
I entered 12 (1st number),
then I entered 15 (2nd number)
and when I press "+" button it should show "12+15=27", is that what you want?
If yes, then it's pretty simple, no complex logic. just store the numbers in two variables (if it's limited to show only last two numbers) and keep shuffling them whenever it receives a new value.
Hope it helps!
