281. Заполни пустые облака: 600 × 3 − 400 =; 342 × 7 + 1000 =; 3049 × 2 − 4000 =; 592 × 8 − 200 × 6 =; 3200 : 4 + 542 × 6 =; 4000 − 2623 × 0 =.

1. \(600 \times 3 - 400 = 1800 - 400 = 1400\).
2. \(342 \times 7 + 1000 = 2394 + 1000 = 3394\).
3. \(3049 \times 2 - 4000 = 6098 - 4000 = 2098\).
4. \(592 \times 8 - 200 \times 6 = 4736 - 1200 = 3536\).
5. \(3200 : 4 + 542 \times 6 = 800 + 3252 = 4052\).
6. \(4000 - 2623 \times 0 = 4000 - 0 = 4000\).

Ответ: 1400; 3394; 2098; 3536; 4052; 4000.
