               print answer
               break
           Case 'S': answer = n1 - n2
               print answer
               break
           Case 'M': answer = n1 * n2
               print answer
               break
           Case 'D': answer = n1 / n2
               print answer
               break
           Case '%': answer = n1 % n2
               print answer
