Careless Xiao Ming mistook the tens digit "7" of the subtrahend as "1" and the single digit "3" of the subtrahend as "8" when calculating a subtraction problem. As a result, the number calculated by Xiao Ming happened to be half of the correct answer. So what should be the correct answer?
粗心的小明在计算一道减法题时，把被减数的十位数字"7"错看成"1"，把减数的个位数字"3"错看成"8"．结果小明算出来的得数恰巧是正确的答案的一半．那么正确的答案应该是多少？
