OK. I guess we will have to think how to resolve this better.

 I would prefer if that respect operator precedence. Well that will not
allow entering something like (3 + 3) * 4 but we can always use scientific
calculator for that.

 Maybe press and hold on something while I suspect that doesn't fall under
regular use as negative numbers represent change not quantity. There is no
need for negative numbers in simple calculator.
