$$72\,960:19$$

$$260\cdot403-(568\cdot5-1\,840)$$

$$87\,220:14$$

$$671\cdot223+(6\,000-87\cdot40)$$

1) $$72\,960 : 19 = 3\,840$$

2) $$87\,220 : 14 = 6\,230$$

3) $$260 \cdot 403 — (568 \cdot 5 — 1\,840)$$

$$568 \cdot 5 = 2\,840$$
$$2\,840 — 1\,840 = 1\,000$$
$$260 \cdot 403 = 104\,780$$
$$104\,780 — 1\,000 = 103\,780$$

4) $$671 \cdot 223 + (6\,000 — 87 \cdot 40)$$

$$87 \cdot 40 = 3\,480$$
$$6\,000 — 3\,480 = 2\,520$$
$$671 \cdot 223 = 149\,633$$
$$149\,633 + 2\,520 = 152\,153$$

Ответ

$$72\,960 : 19 = 3\,840$$
$$87\,220 : 14 = 6\,230$$
$$260 \cdot 403 — (568 \cdot 5 — 1\,840) = 103\,780$$
$$671 \cdot 223 + (6\,000 — 87 \cdot 40) = 152\,153$$
