bonjour
A = - 27 + 35 - 17 + 20
= 55 - 44 = 11
B= - 6.6 + 5.4 - 4.8 + 6.6 - 3.6
= 5.4 - 8.4 = - 3
C = 0.01 x ( - 25 ) x 4 x ( - 13.2 ) x ( - 3 )
= - 39.6
D = 16 + 2 * - 80
= 16 - 160 = - 144
E = - 14 - 75 + 60 = - 29
F = ( - 17 x 2 - 2 ) : 3
= ( - 34 - 2 ) : 3
= - 36 : 3 = - 12
G = 23 + 40 : - 12
= 23 - 40/12
= 23 - 10/3
= 69/3 - 10 /3 = 59/3
