Answer
The set of integers differs from the set of whole numbers by containing negatives of the natural numbers.
Work Step by Step
The set of natural numbers is { 1, 2, 3, 4, 5, ... } .
The set of whole numbers is { 0, 1, 2, 3, 4, 5, ... }
The set of integers is {... , -4, -3, -2, -1,0, 1, 2, 3, 4,...}
The set of integers contains the counting numbers (the natural numbers),
the number zero,
and negatives of the natural numbers.
Negative integers are not in the set of whole numbers.
It differs from the set of whole numbers by containing negatives of the natural numbers.
