Answer 3

Well, sort of. It depends since the definition is sort of ambiguous, and the fact that there is no standard. Some people define it as all of the integers (including 0), since as just the non-negative integers (0,1,2,3,...), and some as just the positive integers (1,2,3,4,...)

Answer 4

-5 is an integer, but -5 is not a whole number

Answer 5

Set of Integers: {..., -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, ...}

basically any number that has no decimal or fractional part


Set of Whole Numbers: {0, 1, 2, 3, 4, 5, 6, 7, ...}

the set of whole number is the set of non-negative (not negative) integers


Set of Natural Numbers: {1, 2, 3, 4, 5, 6, 7, ...}

the set of natural numbers is the set of positive integers



So you can see that there are some integers that aren't whole numbers
