Bonsoir,
(2 + 18) : 2 x 4 - 7 x 5 = 20 : 2 x 4 - 7 x 5 = 10 x 4 - 7 x 5 = 40 - 35 = 5 → E
[(14 - 8) x (49 - 23)] : 12 + 5 = (6 x 26) : 12 + 5 = 156 : 12 + 5 = 13 + 5 = 18 → R
2 x [3 + (15 - 2)] - 11 = 2 x (3 + 13) - 11 = 2 x 16 - 11 = 32 - 11 = 21 → U
(143 - 3 x 12) / (10 x 10 + 49 : 7) = (143 - 36) / (100 + 7) = 107 / 107 = 1 → A
(60 x 2 + 1) / 11 = (120 + 1) / 11 = 121/11 = 11 → K
Le mot est : E U R E K A.
