Bonsoir à tous, j'aimerais un coup de main s'il vous plaît pour ça : calculer les expressions suivantes : A = -3 + 5 - 2 + 1
B = 5 - 4 + 2 - 6
C = -6 + 5 - 4 + 3 - 2 - 1 + 7
D = (+3) - (+2) - (-3) + (-4) + (+6)
E = (-2) + (-5) - (-6) + (+7) - (-3)
F = - (-2) + (-4) - (-6) + (-2) - (-3)
G = (-1) + (-1) - (+1) + (-1) - (+1)

A= -3 + 3 + 1
A= 1
B= 1-4
B= -3
C= -6 + 1 + 1 - 1 + 7
C= -6 + 1 + 7
C= -5 + 7
C= 2
D= 1 - (-3) + (-4) + (-6)
D= 4 + (-4) + (-6)
D= -6
E= -2 + 1 + 10
E= 9
F= -(-2) + 2 + 1
F= 5
G= -1 + (-2) + (-2)
G= -5
Voilà bonne chance

Bonsoir
A = -3 + 5 - 2 + 1
= 2 - 1
= 1
B = 5 - 4 + 2 - 6
= 1 - 4
= -3
C = -6 + 5 - 4 + 3 - 2 - 1 + 7
= -1 - 1 - 2 + 6
= -2 + 4
= 2
D = (+3) - (+2) - (-3) + (-4) + (+6)
= 3 - 2 + 3 - 4 + 6
= 1 + 3 + 2
= 6
E = (-2) + (-5) - (-6) + (+7) - (-3)
= -2 - 5 + 6 + 7 + 3
= -7 + 6 + 10
= -1 + 10
= 9
F = - (-2) + (-4) - (-6) + (-2) - (-3)
= 2 - 4 + 6 - 2 + 3
= -2 + 6 + 1
= -2 + 7
= 5
G = (-1) + (-1) - (+1) + (-1) - (+1)
= -1 - 1 - 1 - 1 - 1
= -5
VOilà j'espère avoir pu t'aider ^^
