Bonjours ,

1)  a)    Programme 1   :   2+6 = 8

                                         8* (-2) = -16

                                          -16+ (2*4) = -8

         Programme 2     :   2-3=  -1

                                        -1*4= -4

                                       -4 - (4) = -8

b)      Programme 1 avec x= -3    :            -3+6 = 3

                                                                  3* (-2) = -6

                                                                  -6+ (-3*4) = -18

      Programme 2  :                   -3 -3 = -6

                                                  -6 *4 = -24

                                                  -24 - (-3*2) =  -18

       Programme 1 avec x= 4    :     4+6 = 10

                                                        10 * (-2) = -20

                                                        -20+ (4*4) = -4

     Programme 2    :                  4-3 = 1

                                                  1 *4 = 4

                                                  4 - ( 2*4) = -4

c)    On remarque que dans chaque cas , pour les deux programme on trouve le même résultats .
