Ответ:

1) \(214 \cdot 104 = 22256\), \(22256 + 7544 = 29800\).

\(29800 \cdot 35 = 1043000\), \(508 \cdot 722 = 366776\).

\(1043000 - 366776 = 676224\).

2) \(255 \cdot 144 = 36720\), \(36900 - 36720 = 180\).

\(647 \cdot 180 = 116460\), \(318 \cdot 92 = 29256\).

\(116460 - 29256 = 87204\).

Ответ: 1) 676224; 2) 87204.
