bonjour
a. 17-2 × (8-4)
= 17 - 2 x 4
= 17 - 8
= 9
c. (135) × (4 + 6)
= 135 x 10
= 1 350
e. 15+(12-3 × 4)
= 15 + ( 12 - 12 )
= 15 + 0
= 15
b. 45:9×(6-2)
= 5 x 4 = 20
d. (19 - 7× 2) + 4
= (19 - 14 ) + 4
= 5 + 4 = 9
f. (50 (13 + 1) × 2) - 6
= ( 50 x 14 ) x 2 - 6
= 1400 - 6 = 1 394
Explications étape par étape :
Bonsoir,
a. 17-2 × (8-4)
= 17-2*( 4)
= 17-8
= 9
c. (135) × (4 + 6)
= 135*10
= 1 350
e. 15+(12-3 × 4)
= 15 + 12-12
= 15
b. 45/9×(6-2)
= 5 *4
= 20
d. (19 - 7× 2) + 4
=19-14 +4
= 9
f. (50 (13 + 1) × 2) - 6
=50* 14*2 -6
= 1 394
