Réponse:
A = [14 - (2+3)] × 2p
A = (14 - 5 ) × 2
A = 9 × 2
A = 18
B = 12 ÷ [(4+2) × 2]
B = 12 ÷ (6 × 2)
B = 12 ÷ 12
B = 1
C = [8 - (7-2)] × 3
C = ( 8 - 5 ) × 3
C = 3 × 3
C = 9
D = 0,5 × [38 - (7+3)]
D = 0,5 × (38 - 10)
D = 0,5 × 28
D = 14
A = (25-7)-8
A = 25 - 7 - 8
A = 10
B = 5 + (49÷7)
B = 5 + 49 ÷ 7
B = 12
C = (3×2)+2×(5-3)
C = 3 × 2 + 2 × 5 - 3
C = 13
D = 6× [(5×2)-4]
D = 6 × ( 5×2) - 4
D = 56
