Answer:

1. The difference of two natural numbers is always an integer. True

Like 6-3=3 and 3-6=-3 both 3 and -3 are integers.

For any two natural numbers a and b, a-b = natural number only when a>b.

Like 5-2=3 is natural but 2-5=-3 is not a natural number.

3. The sum of two natural numbers is always a natural number. True

4. The product of two natural numbers is always a natural number. True

5. The quotient of two natural numbers is always a rational number. True
