bonsoir
Explications étape par étape :
F = 4(12 + 5)
F = 4 x 17
F = 68
G = 6 x 8 + 20
G = 48 + 20
G = 68
H = 9 + 11 x 3
H = 9 + 33
H = 42
I =( 8 + 4) / 6
I = 12/6
I = 2
J = 7 - 25/7
J = (7 x 7)/7 - 25/7
J = (49-25)/7
J = 24/7
K = 9/(7-4)
K = 9/3
K = 3
L = 8 x (15 - 7 )
L = 8 x 8
L = 64
M = (8 x 4) + (7 x 3)
M = 32 + 21
M = 53
N = (15 + 7) x (17 - 5)
N = 22 x 12
N = 264
bonne soirée
