bonjour
tu mettras profil collège et non lycée STP
A = 25 - ( - 2 ) ( - 10 ) = 25 - 20 = 5
B = - ( 7 - 9 ) - 2 ( 4 - 7 ) = - ( - 2) - 2 ( - 3 ) = 2 + 6 = 8
C = - 2 ( 8 - 11 ) + ( 5 - 9 ) = - 2 x - 3 + ( - 4 ) = 6 - 4 = 2
D = ( - 5 - 3 ) ( - 4 - 7 ) = - 8 x - 11 = 88
E = 9 - 42 ² = 9 - 1 764 = - 1 755
F = ( - 2 ) ( - 15 + 5 ) = - 2 x - 10 = 20
