Найдите значения выражений.

• $$2912:8+1200:300-1\cdot144:12$$
• $$(51855+9857):532:58:2\cdot10000$$
• $$102867-867\cdot90+57000:380$$
• $$(207\cdot304-12967+3072:24)\cdot0$$

1) $$2\,912 : 8 + 1\,200 : 300 — 1 \cdot 144 : 12$$

$$2\,912 : 8 = 364$$

$$1\,200 : 300 = 4$$

$$1 \cdot 144 = 144$$

$$144 : 12 = 12$$

$$364 + 4 — 12 = 356$$

2) $$\left(51\,855 + 9\,857\right) : 532 : 58 : 2 \cdot 10\,000$$

$$51\,855 + 9\,857 = 61\,712$$

$$61\,712 : 532 = 116$$

$$116 : 58 = 2$$

$$2 : 2 = 1$$

$$1 \cdot 10\,000 = 10\,000$$

3) $$102\,867 — 867 \cdot 90 + 57\,000 : 380$$

$$867 \cdot 90 = 78\,030$$

$$57\,000 : 380 = 150$$

$$102\,867 — 78\,030 = 24\,837$$

$$24\,837 + 150 = 24\,987$$

4) $$\left(207 \cdot 304 — 12\,967 + 3\,072 : 24\right) \cdot 0$$

$$207 \cdot 304 = 62\,928$$

$$3\,072 : 24 = 128$$

$$62\,928 — 12\,967 + 128 = 50\,089$$

$$50\,089 \cdot 0 = 0$$

Ответ

$$356,\ 10\,000,\ 24\,987,\ 0$$
