Aidez moi c'est l'exercice 109 !!

A = [- 5 - (-8)] x (-2)

A = 3 x (-2)

A = -6

B = 26 - (-9) x 1.5 - 0.5

B = 26 - (-13.5) - 0.5

B=39.5 -05

B = 39 - (-3-2

C= 26 / (-3-2x 5)

C = 26 / (-3 - 10 )

C = 26 / -13

C = -2

a = (-5-(-8) ) x -2 = (-5+8) x-2 = +3 x-2 = -6

b = 26 -(-9) x1.5 -0.5 = 26 +13.5 -0.5 = 39

c = 26 : (-3-2x5) = 26 : (-3-10) = 26 : -13 = 26/-13= -2

d = -4 x0.278x-2x5x-2.5 = -4 x -2.5 x -2x5 x0.278 = +10 x -10 x 0.278

= -100x0.278= -27.8

e = -10 x -8.5 x 0 x -1.5 x -2.5 = 0

pas la peine de faire de calcul tu n as que des mulitplications et un 0 a l interieur donc ton resultat est obligatoirement 0

f = -5 x -8 x -125 x -2 x-1 x -0.5 = -125 x -8 x -5 x-2 x -0.5 x -1 = 1000 x 10 x 0,5 = 1000 x 5 = 5000
