a)  não entendi

b)  {-6+[-4-(2)+3]-2}              c) {-8:[-2-(-2)]+4}      d) +2x2=4     e) {-10+[-8-(-4)]x(-2)}

     {-6+[-4-2+3]-2}                       {-8:[-2+2]+4}                                 {-10+[-8+4]x(-2)}

    {-6+[-3]-2}                                {-8:O+4}                                       {-10+[-4]x(-2)}

    {-6-3-2}                                         =4                                             {-10+(+8)}

     =-11                                                                                                {-10+8}=-2
