When the little sloppy was doing an integer addition problem, he mistakenly regarded the 6 in the unit digit of one addend as 9, and the 3 in the tens digit of the other addition as 5, and the resulting sum was 562. What should be the correct result?
小马虎在做一道整数加法题时，错把一个加数个位上的6看成9，把另一个加数十位上的3看成5，结果得出的和是562．正确的结果应该是多少？
