Answer 1

5 - 10 *2                                           70 - 52 - 60 * 100                6-8 * 2

=5 - 20n                                          =70 - 52 -  600                    =6 - 16

= -15                                               = 18 -600                           = -10

68 + 69 - 58 * 52 -789                       = -582                                5698 + 5648 * 100- 98723

=68 + 69 - 3016 -789                         789 - 789 * 25 -89               =5698 + 564800 - 98723

=(68- 3016) + (69-789)                      =789 - 19725 -89                  = 570498  - 98723

=-2948        +    (-720)                      = (789 - 89 ) - 19725             = 471775

=-3668                                             =  700 - 19725    =  -19025
