bonjour
A = 8× (6 + 14)
= 48 + 112
= 160
B = 65 (21 + 19) 13):9
= manque des signes entre 19 et 13
C = (67 ??
D = (4 + 2×6) × 3
= ( 4 + 12 ) x 3
= 16 x 3 = 48
E = 5x (8 +3×4)
= 5 x ( 8 + 12 )
= 5 x 20 = 100
F = 66 − (7×4+ 22) — 6
= 66 - ( 28 + 22 ) - 6
= 66 - 50 - 6 = 10
G=37- [3×(5 + 2) − 4]
= 37 - [ 3 x ( 7 ) - 4 ]
= 37 - ( 21 - 4 )
= 37 - 17
= 20
H = 15 × [28 - (3 + 3)×3]
= 15 x [ 28 - 6 x 3 ]
= 15 x ( 28 - 12 )
= 15 x 16
= 240
