Bonsoir,
a) ecrire toutes les sommes :
4 + (-3) + 2 = 3
-1 + 1 + 3 = 3
0 + 5 + (-2) = 3
4 + (-1) + 0 = 3
-3 + 1 + 5 = 3
2 + 3 + (-2) = 3
4 + 1 + (-2) = 3
2 + 1 + 0 = 3
b) compléter le carré magique :
S = 2 + (-8) + (-9) + 5
S = (-10)
Dernière ligne :
? + (-7) + 5 + (-2) = (-10)
? = -10 + 4 = (-6)
1ère colonne :
? + (-1) + 0 + (-6) = -10
? = -10 + 7 = (-3)
1ère ligne :
-3 + ? + 2 + 1 = -10
? = -10 + 0 = -10
Première diagonale en partant de la gauche :
-3 + ? + (-9) + (-2) = -10
? = -10 + 14 = 4
2ieme colonne :
-10 + 4 + ? + (-7) = -10
? = -10 + 13 = 3
2ieme ligne :
-1 + 4 + (-8) + ? = -10
? = -10 + 5 = -5
3ieme ligne :
0 + 3 + (-9) + ? = -10
? = -10 + 6 = -4
