Question
bonjour est ce que vous pouriez maider svp ces urgent cette exercice est niveau 5eme
A= (3-5) x (-4) B= [( 12-4 x 5) : 4 ] - 9 C= (20 - 7 + 4 -18) x ( -9 )
D = [ ( 2- ( -5 )) - ( 3-7 )] x 5
A= (3-5) x (-4) B= [( 12-4 x 5) : 4 ] - 9 C= (20 - 7 + 4 -18) x ( -9 )

Bonjour,
⇒ A = ( 3 - 5 ) × (-4)
A = (-2) × (-4)
A = 8
⇒ B = [ ( 12 - 4 × 5) ÷ 4 ] - 9
B = [ ( 12 - 20 ) ÷ 4 ] - 9
B = ( (-8) ÷ 4 ) - 9
B = (-2) - 9
B = (-11)
⇒ C = ( 20 - 7 + 4 - 18 ) × ( -9 )
C = ( 13 + 4 - 18 ) × (-9)
C = ( 17 - 18 ) × (-9)
C = (-1) × (-9)
C = 9
⇒ D = [ ( 2 - ( -5 )) - ( 3 - 7 ) ] × 5
D = [ (-7) - (-4) ] × 5
D = (-3) × 5
D = -15
Bonne journée :)
