The whole numbers are the natural numbers together with 0. (Note: a few textbooks disagree and say the natural numbers include 0 .) The sum of any two natural numbers is also a natural number (for example, 4 + 2000 = 2004 ), and the product of any two natural numbers is a natural number ( 4 × 2000 = 8000 ).

Every natural number can be expressed as a product of prime numbers. If the number is already prime, its decomposition is itself multiplied by one. If not, it is divided into the smallest prime number by which it is divisible (it can be one or several times), until a prime number is obtained. For example: 5 = 5 * 1. 15 = 3 * 5. 28 = 2 * 2 * 7.

Practice Problems on How to Classify Real Numbers. Example 1: Tell if the statement is true or false. Every whole number is a natural number. Solution: The set of whole numbers include all natural or counting numbers and the number zero (0). Since zero is a whole number that is NOT a natural number, therefore the statement is FALSE.

Now we will discuss about the examples of finite sets and infinite sets. Examples of finite set: 1. Let P = {5, 10, 15, 20, 25, 30} Then, P is a finite set and n(P) = 6. 2. Let Q = {natural numbers less than 25} Then, Q is a finite set and n(P) = 24. 3. Let R = {whole numbers between 5 and 45} Then, R is a finite set and n(R) = 38. 4.
