Add your whole numbers
Yes because being closed under an operation means that when the operation is performed on members of a set the result is also a member of the set, and when any two [members of the set of] whole numbers are added together the result of the addition is also a whole number which is, unsurprisingly, a member of the set of whole numbers.
A set can be closed or not closed, not an individual element, such as zero. Furthermore, closure depends on the operation under consideration.
The product of two whole numbers depends on what the numbers are. The operation is multiplication.11 and 8. You find the factors of 88 first. Then find which 2 will subtract to equal 3

Add your whole numbers
Since whole numbers are the same as integers, there are no different rules! The only way in which the rules for natural numbers is different is that the set does not contain the additional opposites of numbers (in other words, the set is not closed under subtraction).

The set of positive whole numbers is not closed under subtraction! In order for a set of numbers to be closed under some operation would mean that if you take any two elements of that set and use the operation the resulting "answer" would also be in the original set.26 is a positive whole number.40 is a positive whole number.However 26-40 = -14 which is clearly not a positive whole number. So positive whole numbers are not closed under subtraction.

Same rules as adding whole numbers with different signs.
They are all numbers and obey the same rules for addition, subtraction, multiplication, division, exponentiation etc.
Integers are whole numbers. 1 3/4 is not a integer whereas 1 is.
That's going to depend on what you want to 'do' to them. Every operation that can be performed with whole numbers can also be performed with fractions.
