Est ce que vous pouvez m’aider svppp merci infiniment Ex 1 :
Calculer :
R = ( -3+9)-(4-11)-(-5-6)
S= -3+12-(13-8)-(3+8)
T= -3-[4-(3-9)]
Calculer :
Ex2 : A = (– 2) × (– 3) × (+ 5)
B = (– 3) × (– 2) × (– 4)
C = (+ 6) × (– 1) × (+ 3)

Bonjour;
Calculer :
R = ( -3+9)-(4-11)-(-5-6)
= 6+7 + 11
= 24
S= -3+12-(13-8)-(3+8)
= -3+12-5-11
= -7
T= -3-[4-(3-9)]
= -3- ( 4+6)
= -3 -10
= -13
Calculer :
Ex2 : A = (– 2) × (– 3) × (+ 5)
= 6*5
= 30
B = (– 3) × (– 2) × (– 4)
= 6*-4
= -24
C = (+ 6) × (– 1) × (+ 3)
= -6 *3
= -18
