Answer 2

markdownCopy code
    59057 ÷ 73 = 809
    239 × 49 = 11711
  + __________
    12520

Therefore, 59057 ÷ 73 + 239 × 49 = 12520.

yamlCopy code
   51642 ÷ (517 + 389) = 54
   7410 + 54 = 7464

Therefore, 7410 + 51642 ÷ (517 + 389) = 7464.

yamlCopy code
   17514 ÷ 21 = 834
   10034 - 834 = 9210
   9210 × 25 = 230250

Therefore, (10034 - 17514 ÷ 21) × 25 = 230250.
