Question
Bonjour, voici mon exercice
Pour les exercices 93 à 95, calculer.
93 A=(-3) - ((+8) − (−9)) + (−3)
B = ((-3) - (+5))+((−1) + (−7))
C = (-7)-((-3) + (+7)) + (-2)
Pour les exercices 93 à 95, calculer.
93 A=(-3) - ((+8) − (−9)) + (−3)
B = ((-3) - (+5))+((−1) + (−7))
C = (-7)-((-3) + (+7)) + (-2)

Bonjour,
Calculer:
A=(-3) - ((+8) − (−9)) + (−3)= -3-(8+9)-3= -3-17-3= -23
B = ((-3) - (+5))+((−1) + (−7))= (-3-5)+(-1-7)= -3-5-1-7= - 16
C = (-7)-((-3) + (+7)) + (-2)= -7-(-3+7)-2= -7-(4)-2= -7-4-2= - 13

Bonsoir
A = (-3) -(8) - (-9) + (-3)
A= -3-8+9-3
A = - 3 -17 -3
A = -20-3
A = -23
B = (-3) -(5) +(-1 ) +( -7 )
B = -3-5-1-7
B = -9-7
B = -16
C = (-7 ) - (-3 ) + (7 ) + (-2 )
C = -7+3+7-2
C = -7+10-2
C = 3-2
C = 1
