Exercice 4: calculer en respectant les priorités :
M = 18+(-9) – 4*(-7)-. 67.8+(-9.)=-2,
A = 3 * (-4) - (-4)=.-12-(-4.) =+8.
T=(-5) 6-(-3) * (-2) =
H=(-6-2 x 2) (-4)= .....
S = (-13 - 2) * (7 - 9) =
M = 18+(-9) – 4*(-7)-. 67.8+(-9.)=-2,
A = 3 * (-4) - (-4)=.-12-(-4.) =+8.
T=(-5) 6-(-3) * (-2) =

Réponse : M= 26
A= -8
T=-36
H=40
S=30
Explications :
M= 18:(-9)-4×(-7) = 18×1/9 +28= 2+28=30
A= 3×(-4)-(-4)=-12-(-4)=-12+4=-8
T=(-5)×6-(-3)×(-2)=-30-6=-36
H=(-6-2×2)×(-4)=(-6-4)×(-4)=-10×(-4)=40
S=(-13-2)×(7-9)=-15×(-2)=30
