is a magic number. Not sure where it is coming from or why. It is possible I missed the reasoning earlier. But it would be good to remove this magic number and replace with a constant. Then the constant could have the description for why 22.

So if you look here, line 355 prevents the calculator display from overflowing; without this line I put in there, the calculator would allow me to keep clicking buttons and thus, overflow the display. That being said, I definitely should replace number 22 with a const variable that clarifies the purpose.

Thanks!
