Bonjour,
voici mes réponses :
B= - 3 × ( - 5)
B= 15
C= (2- 3) × ( -8 )
= -1×(-8)
C= 8
D= 10×5 + 12
= 50 + 12
D= 62
E= (4 - 2) × ( 3 - 5)
= 2×(3-5)
= 2×(-2)
E= -4
F= 3 × (-7) - ( - 18)
= -21+18
F= -3
G= - 10 × ( - 10) - 10
= 100 - 10
G= 90
H= 3×( -7 )
H= -21
J= - 5 × 5 + ( 18 - 3)
= -25 + (18-3)
= -25 + 15
J= -10
I= 100 - 4 × 3 - 1
= 100 - 12 - 1
= 88 - 1
I= 87
