Bonsoir
Savez vous m expliquer les etapes de ces calculs merci énormément

Exercice 2
1°) Calculer les expressions suivantes en écrivant les étapes intermédiaires:
M = (-3 +9) - (4 - 11) - (-5-6)
N=-3-[4-(3-9)]
P = [(+2) - (+ 5)] + [(-7) + (+4)]
R = (-15) - (-8-3) + (6 - (-8))​

Sagot :

M =  (-3+9)-(4-11)-(-5-6)

M =  6-(4-11)-(-5-6)

M =  6-(-7)-(-5-6)

M = 6-(-7)-(-11)

M = 13-(-11)

M = 24

N = -3-[4-(3-9)]

N = -3-[4-(-6)]

N = -3-10

N = -13

P =  [(+2) - (+ 5)] + [(-7) + (+4)]

P =  [(+2) - (+5)] +(-3)

P =  -3 +(-3)

P =  -6

R = (-15) - (-8-3) + (6 - (-8))

R = - 4 + 14

R = 10
