Найдите значения выражений.

• $$100\,000 \cdot 9 — (3\,828 + 14\,963)$$
• $$756 : 108 \cdot 1\,000\,000 — 6\,995$$
• $$308 \cdot 10\,000 — (970 : 10) \cdot 1000$$
• $$1\,039 \cdot 10 + 1\,039 \cdot 100 + 1\,039 \cdot 1\,000$$

1) $$100\,000 \cdot 9 — (3\,828 + 14\,963)$$

$$3\,828 + 14\,963 = 18\,791$$

$$100\,000 \cdot 9 = 900\,000$$

$$900\,000 — 18\,791 = 881\,209$$

2) $$756 : 108 \cdot 1\,000\,000 — 6\,995\,308$$

$$756 : 108 = 7$$

$$7 \cdot 1\,000\,000 = 7\,000\,000$$

$$7\,000\,000 — 6\,995\,308 = 4\,692$$

3) $$358 \cdot 10\,000 — (970 : 10) \cdot 1\,000$$

$$970 : 10 = 97$$

$$358 \cdot 10\,000 = 3\,580\,000$$

$$97 \cdot 1\,000 = 97\,000$$

$$3\,580\,000 — 97\,000 = 3\,483\,000$$

4) $$1\,039 \cdot 10 + 1\,039 \cdot 100 + 1\,039 \cdot 1\,000$$

$$1\,039 \cdot 10 = 10\,390$$

$$1\,039 \cdot 100 = 103\,900$$

$$1\,039 \cdot 1\,000 = 1\,039\,000$$

$$10\,390 + 103\,900 = 114\,290$$

$$114\,290 + 1\,039\,000 = 1\,153\,290$$

Ответ

$$881\,209;\ 4\,692;\ 3\,483\,000;\ 1\,153\,290$$
