Bonjour

-10 | -5 | A | -1

1 ...| 0 | -11 | B

C | D | 3 | E

4 | F | G | -7

Somme :

-10 + 0 + 3 - 7 = -17 + 3 = -14

-10 - 5 + A - 1 = -14

A = -14 + 16

A = 2

2 - 11 + 3 + G = -14

G = -14 + 11 - 5

G = -19 + 11

G = -8

4 + F - 8 - 7 = -14

F = -14 + 15 - 4

F = -18 + 15

F = -3

-5 + 0 + D - 3 = -14

D = -14 + 8

D = -6

1 + 0 - 11 + B = -14

B = -14 + 11 - 1

B = -15 + 11

B = -4

-1 - 4 + E - 7 = -14

E = -14 + 12

E = -2

C - 6 + 3 - 2 = -14

C = -14 + 8 - 3

C = -17 + 8

C = -9

-10 | -5 | 2 | -1

1 | 0 | -11 | -4

-9 | -6 | 3 | -2

4 | -3 | -8 | -7
