Bonjour
Compléter ce carré magique :
A | B | 2 | 1
-1 | C | -8 | D
0 | E | -9 | F
G | -7 | 5 | -2
Somme :
2 - 8 - 9 + 5 = 7 - 17 = -10
G - 7 + 5 - 2 = -10
G = -10 + 7 + 2 - 5
G = -15 + 9
G = -6
A - 1 + 0 - 6 = -10
A = -10 + 1 + 6
A = -10 + 7
A = -3
-3 + B + 2 + 1 = -10
B = -10 + 3 - 2 - 1
B = -13 + 3
B = -10
-3 + C - 9 - 2 = -10
C = -10 + 3 + 9 + 2
C = -10 + 14
C = 4
-10 + 4 + E - 7 = -10
E = -10 + 10 - 4 + 7
E = 3
-1 + 4 - 8 + D = -10
D = -10 + 1 - 4 + 8
D = -14 + 9
D = -5
1 - 5 + F - 2 = -10
F = -10 - 1 + 5 + 2
F = -11 + 7
F = -4
-3 | -10 | 2 | 1
-1 | 4 | -8 | -5
0 | 3 | -9 | -4
-6 | -7 | 5 | -2
