Решение:
A)
- \( 35 + (53 - 28) - 14 = 35 + 25 - 14 = 60 - 14 = 46 \)
- \( (37 + 43) - 24 + 12 = 80 - 24 + 12 = 56 + 12 = 68 \)
Б)
- \( 58 - 18 + 65 = 40 + 65 = 105 \)
- \( 15 - 7 + 78 = 8 + 78 = 86 \)
B)
- \( (18 - 9) \times 4 = 9 \times 4 = 36 \)
- \( 4 \times 8 - 15 = 32 - 15 = 17 \)
Ответ: A) 46, 68; Б) 105, 86; B) 36, 17.
