Explications étape par étape
Bonjour
Carré magique multiplicatif :
18 | A | B
C | -6 | D
-3 | E | 2
Produit : 18 x -6 x 2 = -216
18 x C x (-3) = -216
C = -216/(-18 x 3)
C = 216/54
C = 4
4 x (-6) x D = -216
D = -216/(4 x -6)
D = 216/24
D = 9
B x 9 x 2 = -216
B = -216/(2 x 9)
B = -216/18
B = -12
18 x A x -12 = -216
A = -216/(-18 x 12)
A = 216/216
A = 1
-3 x E x 2 = -216
E = -216/(-3 x 2)
E = 216/6
E = 36
18 | 1 | -12
4 | -6 | 9
-3 | 36 | 2
-15 | A | -2 | 6
B | C | -5 | D
-3 | 6 | E | 5
7 | -10 | F | G
Produit : 7 x 6 x (-5) x 6 = (-1260)
-3 x 6 x E x 5 = -1260
E = -1260/(-3 x 6 x 5)
E = 1260/90
E = 14
-2 x -5 x 14 x F = -1260
F = -1260/(-2 x -5 x 14)
F = -1260/140
F = -9
7 x -10 x -9 x G = -1260
G = -1260/(7 x 10 x 9)
G = -1260/630
G = (-2)
-15 x C x 14 x (-2) = -1260
C = -1260/(15 x 14 x 2)
C = -1260/420
C = 3
-15 x A x (-2) x 6 = -1260
A = -1260/(15 x2 x 6)
A = -1260/180
A = -7
-15 x B x -3 x 7 = -1260
B = -1260/(15 x 3 x 7)
B = -1260/315
B = -4
-4 x 3 x -5 x D = -1260
D = -1260/(4 x 3 x 5)
D = -1260/60
D = -21
-15 | -7 | -2 | 6
-4 | 3 | -5 | -21
-3 | 6 | 14 | 5
7 | -10 | -9 | -2
