Basic Concepts of Number System

Number system comprises of 10 digits (0, 1, 2,3,4,5,6,7,8,9 ).  When these digits are grouped together it becomes a number. When the value of the digits varies according to their placements it is termed as Place Value, however, when the value of digit remains the same irrespective of its place, it is termed Face Value.  

Types of Numbers:

1. Natural Numbers: Positive numbers (1,2,3,4,5,6……) beginning from 1 that can be counted are known as Natural Numbers. These numbers are also known as Positive Integers.
2. Whole Numbers: All the numbers that can be counted including zero ( 0,1,2,3,4….) are known as Whole Numbers.
3. Integers: All the numbers that can be counted (positive and negative) and 0 are Integers. …-3,-2,-1,0,1,2,3…. Positive Integers: Positive numbers including zero 0,1,2,…. Negative Integers: Negative numbers ….-4,-3,-2,-1
4. Rational Number: Number that can be expressed in the format of (a/b) where b≠0 is a rational number. This includes all integers, zero or fraction.
5. Irrational Numbers: Numbers that cannot be expressed in proper (a/b) format are irrational numbers. For eg: π = 1415926535897932384626433832795028… And this value of pi never terminates and we use 3.14 or 22/7 (where 22/7 is an irrational number). That’s why irrational numbers are also known for their recurring property.
6. Even Numbers: Integers (+ve & -ve) that can be divided by 2 are even numbers
7. Odd Numbers: Integers that cannot be divided by 2 are odd numbers
8. Prime Numbers: Positive Integers that have only two factors 1 and itself are Prime numbers. It is advisable to know all 25 prime numbers below 100 i.e., 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 & 97.
9. Composite Number: All the numbers that are not prime are Composite Numbers.
10. Co- Prime Numbers: Two numbers that have HCF as 1 i.e, no other common factor exists between them are called Co- Prime Numbers. Ex: 5 and 24
11. Real Number: All the numbers discussed above comes under the umbrella of Real numbers. These numbers can be represented in the number line.
