| S. No | Type of Numbers | Description |
| 1 | Natural Numbers | N = {1,2,3,4,5 > It is the counting numbers |
| 2 | Whole number | W= {0,1,2,3,4,5> It is the counting numbers + zero |
| 3 | Integers | All whole numbers including Negative number + Positive number ……-4,-3,-2,-1,0,1,2,3,4,5… so on. Like whole numbers, integers don’t include fractions or decimals. |
| 4 | Positive integers | Z+ = 1,2,3,4,5, …… |
| 5 | Negative integers | Z– = -1,-2,-3,-4,-5, …… |
| 6 | Rational Number | A number is called rational if it can be expressed in the form p/q where p and q are integers (q> 0). Ex: P/q, 4/5 |
| 7 | Irrational Number | A number is called rational if it cannot be expressed in the form p/q where p and q are integers (q> 0). Ex: √2, Pi, … etc |
| 8 | Real Numbers | A real number is a number that can be found on the number line. Real Numbers are the numbers that we normally use and apply in real-world applications. Real Numbers include Natural Numbers, Whole Numbers, Integers, Fractions, Rational Numbers and Irrational Numbers |
