-2 | 4 | -7 | D
E | F | -4 | G
Somme :
3 + 2 - 7 - 4 = 5 - 11 = (-6)
A + 6 + 3 - 3 = -6
A = -6 - 6
A = -12
6 - 5 + 4 + F = -6
F = -6 + 6 + 5 - 4
F = 1
-2 + 4 - 7 + D = -6
D = -6 + 2 - 4 + 7
D = -10 + 9
D = -1
-3 + 2 + 4 + E = -6
E = -6 + 3 - 2 - 4
E = -12 + 3
E = -9
-12 + B - 2 - 9 = -6
B = -6 + 12 + 2 + 9
B = -6 + 23
B = 17
17 - 5 + 2 + C = -6
C = -6 - 17 + 5 - 2
C = -25 + 5
C = -20
-3 - 20 - 1 + G = -6
G = -6 + 3 + 20 + 1
G = -6 + 24
G = 18
