Ответ:
\((228 + 757) \cdot 74 + 581 \cdot 618\)
\(228 + 757 = 985\), \(985 \cdot 74 = 72890\).
\(581 \cdot 618 = 581 \cdot (600 + 18) = 348600 + 10458 = 359058\).
\(72890 + 359058 = 431948\).
\((1125 + 875) \cdot 18 + 4328\)
\(1125 + 875 = 2000\), \(2000 \cdot 18 = 36000\).
\(36000 + 4328 = 40328\).
\(19867 + (76535 - 40596) : 3 - 7894\)
\(76535 - 40596 = 35939\).
\(35939 : 3 = 11979\frac{2}{3}\).
\(19867 + 11979\frac{2}{3} - 7894 = 23952\frac{2}{3}\).
Ответ: 431948; 40328; 23952\(\frac{2}{3}\).
