Do you ever get confused about the difference between integers and real numbers? How about rational and irrational numbers? In this video we take a look at how the different types of numbers are related.

**The Different Types of Numbers**

**Natural Numbers:** *also called counting numbers, *

*starts at $1$ and continues from there.*

* Ex.* $1, 2, 3, 4, 5 …$

**Whole Numbers: **

*include all the natural numbers and zero.*

*Ex.*$0,1, 2, 3, 4, 5 …

** Integers: **

*include all the whole numbers and their opposites.*

*Ex.*$… -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5…$

**Rational Numbers:*** include any number that can be written as a fraction. This includes all the integer, and both **terming both repeating and terminating decimals. *

* Ex. *$(-2, -1.5, -1, 0, 0.25, 1, 1\tfrac{7}{8}, 2.\overline{\rm 3})$

**Irrational Numbers: ***are non-repeating decimals. (Numbers that can’t be written as a fraction.)
Ex. *$ \sqrt{2}, \sqrt{3}, \Pi , \varphi $

**Real Numbers:**

*Include both rational and irrational numbers.*

**Imaginary Numbers:** *A number when squared gives you a negative answer. It is called imaginary number because there is no real number that when you square it becomes negative. i represent the $ \sqrt{-1}$.*
