Sagot :
Bonjour,
15 - (10 - 6) = 15 - 4 = 11
5 * (14/4) = 5 * 3.5 = 17.5
11 + 4 * (3 + 2) = 11 + 4 * 5 = 11 + 20 = 31
(2 + 7) * (13 - 2) = 9 * 11 = 99
Bonjour
A = 15 - (10 - 6)
A = 15 - 4
A = 11
B = 5 × (14 : 4)
B = 5 × 3,5
B = 17,5
C = 11 + 4 × (3 + 7)
C = 15 × 10
C = 150
D = (2 + 7) × (13 - 2)
D = 9 × 11
D = 99
N'hésite pas si tu as des questions à mes les poser en commentaires :)
