Example 1:

        Perform the following calculations,


            1. (12.638 + 3.5984  ) + (−4.884 − 15.32  )
            2. (−6.284 − 2.223  ) + (7.83 − 14.3  )

            3. (1.118 + 3.58  ) + (−2.24 + 14.28  )

            4. (−63.92 − 52.3  ) + (45.82 + 67.2  )
            5. (1.139 + 2.225  ) + (−3.57 + 9.21  )


        Express these calculations in the general form

                                          +   


        where A and B are complex. The keystrokes from your

        fx calculator are ((MODE)2),
