Решение:
- \( 74 \times 62 = 4588 \)
- \( 1500 : 50 = 30 \)
- \( 4588 + 30 = 4618 \)
- \( 89 \times 53 = 4717 \)
- \( 910 : 26 = 35 \)
- \( 4717 + 35 = 4752 \)
- \( 76 \times 81 = 6156 \)
- \( 1680 : 56 = 30 \)
- \( 6156 + 30 = 6186 \)
- \( 112 \times 58 = 6496 \)
- \( 720 : 36 = 20 \)
- \( 6496 + 20 = 6516 \)
Ответ: 4618, 4752, 6186, 6516.
