(1) Natural numbers are the counting numbers: 1, 2, 3, 4, …. so on.
∴ The smallest natural number is 1.

(2) Whole numbers include all the natural numbers including 0.
There are infinite whole numbers.
∴ We cannot determine the biggest whole number.

There are infinite negative integers and infinite positive integers.
∴ We cannot determine the smallest integer.
