Réponse:

M = 6 + [4 x (2 + 7)] = 6 + [4 x 9] = 6 + 36 = 42

N = [(14.5 x 2) + 3.5] x 2 = (29 + 3.5) x 2 = 32.5 x 2 = 65

O = (124) + 2 = 126

P = 12 ÷ (4 + 2) = 12 ÷ 6 = 2

tu pouvais faire un effort !

Bonjour;

M= 6 +[ 4*9]

= 6+ 36

= 42

N= [ 29 +3,5] *2

= 32,5*2

= 65

O=  3+2

= 5

P =  12/ 6

= 2
