Ответ:

а) \(12\,348 - 127 \cdot 45 + 25 \cdot (983 - 485)\)

\(983 - 485 = 498\)

\(127 \cdot 45 = 5715\)

\(25 \cdot 498 = 12\,450\)

\(12\,348 - 5715 + 12\,450 = 19\,083\)

б) \(44\,245 + 9365 : 5 \cdot 24 - 55\,205\)

\(9365 : 5 = 1873\)

\(1873 \cdot 24 = 44\,952\)

\(44\,245 + 44\,952 - 55\,205 = 33\,992\)

Ответ: а) 19 083; б) 33 992.
