Question 1183595
<font face="Times New Roman" size="+2">


The thing is, given the more restrictive definition of Whole Numbers, i.e., the non-negative integers, neither of the numbers can be negative, but there is absolutely nothing about the problem that either says or implies that the <i>difference</i> must be non-negative.  Hence, using the more restrictive definition, the first number could well be zero and the second 45, making a difference of -45 which is most certainly less than 10.  Therefore the range of the first number is 0 to 27 and the range of the second is 18 to 45.
