+ [Impact]
+ 
+ This bug gives wrong results when undo is used.
+ 
+ [Test Case]
+ 
+ 1. Open calculator and type "5000/60" followed by <Enter>. The
+ calculator produces the right answer, 83.333...
+ 
+ 2. Type "/60" followed by <Enter> to divide by 60 again. The calculator
+ again produces the right answer, 1.388...
+ 
+ 3. Press <ctrl>-Z to undo the last calculation.
+ 
+ 4. Press <backspace> twice to delete the last "60".
+ 
+ 5. Type "12" followed by <Enter>, to divide by 12 instead.
+ 
+ The calculator gives the wrong answer.
+ 
+ [Regression Potential]
+ 
+ The fixes themselves could introduce new bugs.

  -----------------------------------------------------------------------------
  
  I found this bug trying to redo a calculation. Do a calculation maybe
  with decimals like I did and then press CTRL+Z and hit enter and you
  should see the bug.
  
  It's making a bad calculation after these steps.
