Work Step by Step

The set of whole numbers consists of both 0 and all natural numbers (also known as the positive counting numbers). The set of integers consists of both 0 and all negative/positive numbers that can be expressed without using a decimal (such as -2, 0, and 600). Therefore, we know that every whole number is an integer, because every whole number can be expressed as a number without using a decimal. For example, 10, 125, and $\sqrt 16(=4)$ are all whole numbers that are also integers.
