Ответ:

  1. 197 × 5 = 985
  2. 216 × 4 = 864
  3. 307 × 3 - 704 : 8 = 921 - 88 = 833
  4. 65 × 8 - 535 : 5 = 520 - 107 = 413
  5. 684 : 9 + (506 - 102 × 3) = 76 + (506 - 306) = 76 + 200 = 276
  6. 736 : 4 + (607 - 428 : 4) = 184 + (607 - 107) = 184 + 500 = 684

Ответ: 1) 985; 2) 864; 3) 833; 4) 413; 5) 276; 6) 684.
