Задача

8 · 24 372 — (12 143 + 11 778) · 7
100 · (11 372 — 10 599) · 6 + 19 060 · 4
(24 375 — 3 979) · 8 + 90 · 10 : 5
180 : 12 · 1 000 — 906 : 3 + 3 007 · 2

Подробный ответ

1) $$8 \cdot 24\,372 — (12\,143 + 11\,778) \cdot 7$$

$$12\,143 + 11\,778 = 23\,921$$

$$8 \cdot 24\,372 = 194\,976$$

$$23\,921 \cdot 7 = 167\,447$$

$$194\,976 — 167\,447 = 27\,529$$

2) $$100 \cdot (11\,372 — 10\,599) \cdot 6 + 19\,060 \cdot 4$$

$$11\,372 — 10\,599 = 773$$

$$100 \cdot 773 = 77\,300$$

$$77\,300 \cdot 6 = 463\,800$$

$$19\,060 \cdot 4 = 76\,240$$

$$463\,800 + 76\,240 = 540\,040$$

3) $$(24\,375 — 3\,979) \cdot 8 + 90 \cdot 10 : 5$$

$$24\,375 — 3\,979 = 20\,396$$

$$20\,396 \cdot 8 = 163\,168$$

$$90 \cdot 10 = 900$$

$$900 : 5 = 180$$

$$163\,168 + 180 = 163\,348$$

4) $$180 : 12 \cdot 1\,000 — 906 : 3 + 3\,007 \cdot 2$$

$$180 : 12 = 15$$

$$15 \cdot 1\,000 = 15\,000$$

$$906 : 3 = 302$$

$$3\,007 \cdot 2 = 6\,014$$

$$15\,000 — 302 = 14\,698$$

$$14\,698 + 6\,014 = 20\,712$$
