Example 1: A **natural number** is also awhole**number**. The set of whole **numbers** includesthe**number** zero and all **natural numbers**. The setofintegers is composed of the **number** zero,**naturalnumbers**, and the “negatives” of**naturalnumbers**. That means some integers are whole**numbers**, butnot all.
