Add just like you learned to add in kindergarten or 1st grade, e.g.
1+1 = 2
48 + 35 = 83
A product of a given whole number and another whole number = whole numbers
Another whole number.Specifically, it's what you get when you multiply the 2 numbers together.
Yes. When you add any whole numbers you get another whole number. That is what closed means in this context. The answer is still a whole number.
The second number is a factor of the first.
No, whole numbers are not closed under division. It is possible to divide one whole number by another whole number and get a result which is not a whole number, for example, 1/2. One divided by two is a half.
56 is a rational whole natural number. Or to put it another way: 56 is a Natural number, but as all natural numbers are also whole numbers 56 is also a whole number, but as all whole numbers are also rational numbers 56 is also a rational number. Natural numbers are a [proper] subset of whole numbers; Whole numbers are a [proper] subset of rational numbers. The set of rational numbers along with the set of irrational numbers make up the set of real numbers
If two whole numbers are consecutive, that means there can't be another whole number between them.
All the whole numbers have a number 3 above and another number 3 below, with a difference 3 from the whole number. So that's infinite.
No, it is not, because whole numbers must be positive.
The product of a whole number and another whole number is a whole number.
A rational number can be written as (one whole number) divided by (another whole number). An irrational number can't.
No, the result of a division of one whole number into another might be a whole number, but could also be a fraction.
