This very Disagreeable calculator will produce the integers 1 through 20.

Tabulate your response ¹, eg:
aaaaaa1aaa A
aaaaaa2aaa AA
aaaaaa3aaa AAA ...

Please press "Clear" to start², and at any time to reset the display.


Note
1. The example response table is clearly not correct!
2. If you invoked a time/date stamp please press "Clear".
3. Use your keying as efficiently as possible.

Daniel, you wrote:
For instance pressing A gives 1, pressing AA gives 1-2*1=-1, and pressing it a 3rd time goes back to adding its value thus AAA gives 1-2*1+1=0 and pressing a button continuosly repeats this pattern.

Charlie picked up on your responses for 2 and 6.
You somehow didn't adhere to your own analysis.

May I also ask you to clear the display and then continually press (say, 5 or 6 times) 3 , and do a repeat for the 7.  Is there something different to repeatedly pressing the 1?

That said.  You determined the operation of the device correctly.
