(6 points)
Calculer les expressions suivantes :
A = (-4) + (-5) + (+2)+(-7) + (-1)
B = (-3,5) - (-2) + (-2,5) - (+3)
D = (2 - 5)-(4+3 x (-2))
C = (4 - 2) = 2 +1 (-4)
F = (-4) (-2) (-1) (+1) (-2)
E =1-(2+3 X(-1))
Justifier les calculs A, B, C, D et E.
Bonsoir possible d avoir un petit coup de pouce svp

Bonsoir,
A = (-4) + (-5) + (+2)+(-7) + (-1)
= -4-5+2-7-1 =?
B = (-3,5) - (-2) + (-2,5) - (+3)
= -3,5+2-2,5-3 =?
D = (2 - 5)-(4+3 x (-2))
2-5 -4+6= ?
C = (4 - 2) + 2 +1 (-4)
= 4-2 +2 -4 =?
F = (-4) (-2) (-1) (+1) (-2)
= + 16
E =1-(2+3 X(-1))
= 1-2-3 = ?
Je te laisse afire les opérations
Justifier les calculs A, B, C, D et E.
