- Identify the different types of numbers in the real number system.

__What is the real number system?__

The real number system consists of numbers that fall on the number line. This means that the real number system consists of EVERY number in the universe!

Numbers play an important part in the real world by assigning values and weighing variables. We use the real number system every day. The real number system is broken down into two kinds of numbers: rationals and irrationals. We can further break down rational numbers into integers, whole numbers, and natural numbers.

We can also demonstrate the real number system by creating a tree diagram.
