683737+(-39383):9-9

To solve this expression, we need to follow the order of operations (also known as PEMDAS).

First, let's simplify the addition and subtraction within the parentheses: 683737 + (-39383) = 644354

Now, let's do the division and subtraction outside the parentheses: 644354 / 9 = 71661.555556

Finally, subtract 9 from the previous result: 71661.555556 - 9 = 71652.555556

Therefore, the final answer is 71652.555556.
