Difference of two whole number is not always a whole number.
For any two whole numbers a & b, a - b = whole number only when a is greater than or equal to b.

Even if a is less than b, the difference is still a whole number. Whole numbers can be negative.
So the correct answer to the question is "YES".
Yes, the difference between two even numbers is always an even number.
Yes, it is.
No. If the two numbers are integers, then on average, only about half the number of times.For example, the difference between 1 and 4 is 3.
The different between two different odd numbers are always an even number
Yes, the difference of two whole numbers is always a whole number.
No, it is not always so.
The question cannot be answered because it is nonsensical. The difference between two rational numbers is very very rarely a whole number.
No. 5 and 2 are real numbers. Their difference, 3, is a rational number.
No. The difference can be a negative integer which is not a natural number.
If you are talking about integers on the number line, the answer is 1. If you are talking about real numbers, then there is always a real number between every other two, so you can't really talk about the difference.
