a. -8-30+5 = -38+5 = -33
b. (-7x3-5) x2= (-21-5)x2 = -26x2 = -52
c. -20+8 / -3 = -12/ -3 = 4
d. 12+24/ -6 = 36/-6 = -6

A = -8 + 10 * (-3) + 5 B = ( -7 * 3 -5) * 2
A = -8 + (-30) +5 B = -21 -5 * 2
A = -38 +5 B = -26 * 2
A = -33 B = -52

C = -4 * 5 + 8/ -2 - 1 D = 12 - -24/ -3 * 2
C = -20 +8/ -2 - 1 D= 12 + 24/ -3 * 2 C = -20 + 8/ -3 D = 12 + 24/-6
C = -28/3 D = 36/-6

et voila c'est fini
