Bonsoir, j’ai besoin d’aide pour l’exercice 76. Merci d’avance.

bonjour

Explications étape par étape:

1)

a. cellule B2 / = 0 x 9 = 0 - 8 = -8

cellule C2 / = 1 x 9 = 9 - 8 = 1

cellule D2 / = 2 x 9 = 18 - 8 = 10

cellule E2 / = 3 x 9 = 27 - 8 = 19

cellule F2 / = 4 x 9 = 36 - 8 = 28

cellule G2 / = 5 x 9 = 45 - 8 = 37

cellule H2 / = 6 x 9 = 54 - 8 = 46

cellule I2 / = 7 x 9 = 63 - 8 = 55

cellule J2 / = 8 x 9 = 72 - 8 = 64

cellule K2 / = 9 x 9 = 81 - 8 = 73

cellule L2 / = 10 x 9 = 90 - 8 = 82

b.cellule B3 / = 0 x (-3)= 0 + 31 = 32

cellule C3 / = 1 x (-3) = -3 + 31 = 28

cellule D3 / = 2 x (-3) = -6 + 31 = 25

cellule E3 / = 3 x (-3) = -9 + 31 = 22

cellule F3 / = 4 x (-3) = -12 + 31 = 19

cellule G3 / = 5 x (-3) = -15 + 31 = 16

cellule H3 / = 6 x (-3) = -18 + 31 = 13

cellule I3 / = 7 x (-3) = -21 + 31 = 10

cellule J3 / = 8 x (-3) = - 24 + 31 = 7

cellule K3 / = 9 x (-3) = -27 + 31 = 4

cellule L3 / = 10 x (-3) = -30 + 31 = 1

2)

a. Si Mathilde et Paul veulent avoir le même résultat il faudrait avoir le même programme de calcul.

b. Le nombre de départ serait le 1.

1 x 9 = 9

1 x 9 = 9
