bonjour
A = 24 - 3 x 6 + 8 - 72 : ( - 2 )
= 24 - 18 + 8 + 36
= 68 - 18
= 50
B = - 38 + 8 x 3 - 9 + 12 : ( - 2 )
= - 38 + 24 - 9 - 6
= 24 - 53 = - 29
C = - ( 14 + 3 x 2 ) + 13 - 15
= - ( 14 + 6 ) + 13 - 15
= - 20 + 13 - 15
= 13 - 35 = - 22
G = 4 a - 3 b + c
G = 4*- 2 - 3 *3 - 5
= - 8 - 9 - 5 = - 22
H = - 3 * ( - 2 ) + 4 ( - 4 ) - ( - 5 )
= 6 - 16 + 5 = - 4
I = - ( - 2 + 3 ) + 3 ( - 5 )
= - 1 - 15 = - 16
J = ( - 2 - 3 ) ( - 5 - 4 )
= - 5 * - 9 = 45
