12-6+5 = 12-11 = 1
5x[4+(2+3x6)] = 5x(4 + 20) = 20 + 100 = 120
24-6:2 = 24-3 = 21
42-4x9 = 42-36 = 6
(+7)-(-3+5)+(4-(3)) = 7 +3 - 5 + 4 - 3 = 7+4-5 = 11-5 = 6
(-2)-[2-(3=-3+5)] = -2 -2 + (3?2) = -4 + 3?2
Détaillez et calculez : 12-6+5 / 5x[4+(2+3x6)] / 24-6:2 / 42-4x9
(+7)-(-3+5)+(4-(3)) / (-2)-[2-(3=-3+5)]
12-6+5 = 12-11 = 1
5x[4+(2+3x6)] = 5x(4 + 20) = 20 + 100 = 120
24-6:2 = 24-3 = 21
42-4x9 = 42-36 = 6
(+7)-(-3+5)+(4-(3)) = 7 +3 - 5 + 4 - 3 = 7+4-5 = 11-5 = 6
(-2)-[2-(3=-3+5)] = -2 -2 + (3?2) = -4 + 3?2
