A = (2- 9) + (4-7) - 2
B = 6-(3-8) + (6 + 4)
C = -7- [8 + (-3)]
D: 4 X 5 - 16 : 4
E = 30: (4 + 11) - 40​

Bonjour

A = (2- 9) + (4-7) - 2

A = (- 7) + (- 3) - 2

A = - 7 - 3 - 2

A = - 12

B = 6-(3-8) + (6 + 4)

B = 6 - (- 5) + 10

B = 6 + 5 + 10

B = 21

C = -7- [8 + (-3)]

C = - 7 - 5

C = - 12

D: 4 X 5 - 16 : 4

D = 20 - 4

D = 16

E = 30: (4 + 11) - 40​

E = 30 : 15 - 40

E = 2 - 40

E = - 38.
