Ответ:

  1. \(35\,659-12\,459=23\,200\).

    \(23\,200-17\,282=5\,918\).

  2. \(46\,854+15\,446=62\,300\).

    \(62\,300-53\,248=9\,052\).

  3. \(4\,756+3\,859=8\,615\).

    \(8\,615-1\,508=7\,107\).

    \(29\,006-28\,997=9\).

    \(7\,107-9+3\,188=7\,098+3\,188=10\,286\).

Ответ: 1) 5 918; 2) 9 052; 3) 10 286.
