Bonjour,
Calculer en respectant les priorités :
I = - 1 + 2 - 3 + 4 - 5 + 6 - 7 + 8
I = - 1 - 3 - 5 - 7 + 2 + 4 + 6 + 8
I = - 16 + 20
I = 4
J = - ( 1 + 2 ) - ( 3 + 4 ) - ( 5 + 6 ) - ( 7 + 8 )
J = - 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8
J = 36
K = - 1 + ( 2 - 3 + 4 ) - ( 5 + 6 - 7 ) + 8
K = - 1 + 2 - 3 + 4 - 5 - 6 + 7 + 8
K = - 1 - 3 - 5 - 6 + 2 + 4 + 7 + 8
K = - 15 + 21
K = 6
L = [( - 1 + 2) - ( 3 + 4 )] - [( 5 + 6 ) - ( 7 + 8 )]
L = (- 1 + 2 - 3 - 4) - (5 + 6 - 7 - 8)
L = (- 8 + 2) - (- 4)
L = - 6 + 4
L = - 2.
