Bonjour
Calculer i = (-25)-(+17)-(-13)+(+21) = -25 -17 +13 +21 = 34 - 42 = - 8
Calculer j = (+14)+(-33)+(-16)+(+42) = 14 -33 -16 +42 = 56 - 49 = + 7
Calculer k = (-23)+(-31)-(+44)+(-36)-(-28) = -23 -31 -44 -36 +28 = 28 - 134 = - 106
Calculer l = (+18)-(+34)+(-14)-(-27)+(-35) = 18 -34 -14 +27 -35 = 45 - 83 = - 38
