Решение:
- \( 875 - 496 = 379 \)
- \( 563 + 289 = 852 \)
- \( 602 + 398 = 1000 \)
- \( 840 : 4 = 210 \)
- \( 960 : 3 = 320 \)
- \( 720 : 4 = 180 \)
- \( 276 \times 2 = 552 \)
- \( 148 \times 3 = 444 \)
- \( 320 \times 3 = 960 \)
- \( 48 : 6 \times 7 = 8 \times 7 = 56 \)
- \( 32 : 4 \times 9 = 8 \times 9 = 72 \)
- \( 28 : 7 \times 6 = 4 \times 6 = 24 \)
Ответ: 379, 852, 1000, 210, 320, 180, 552, 444, 960, 56, 72, 24.
