1.   Natural or Counting Numbers

The sequence of integers:

[1] 1, 2, 3, 4, … n, (n+1), … is called, Natural or Counting Numbers.

The sequence [1] does not have a maximum number. No matter how large  “n” is, there is always a number “n + 1” larger than “n”.

 

2.  Number Zero

Number zero (0)  is the number equal to nothing.

 

3. Whole Numbers

are the numbers that  contain Natural Numbers and  Number Zero.

The sequence of integers:

0,1, 2, 3, 4, … n, (n+1), …  is called Whole Numbers.

 

4.  Integers

The sequence:

[2] … – (n + 1), – n, … -4, – 3, -2, -1, 0, 1, 2, 3, 4, … n, (n+1), … is a sequence of integers.

The sequence [2] does not have a minimum or maximum number. No matter how small “– n”  is, there is always a number  “– (n+1)”  smaller than  “– n”  and no matter how large  “n” is, there is always a number “n + 1” larger than “n”.

 

4.1.  Prime numbers

A prime number is an integer that can be divided only by itself and by 1.

Example of prime numbers:  2; 3; 5; 7; 11; 13; 17; 19; 23; 29; 31; 37; 41; 43; 47  and so on.

Note: 0 and 1 are not considered prime numbers.

 

4.2.  Odd numbers

An odd number is an integer that cannot be divided by 2.

Example of odd numbers:  1; 3; 5; 7; 9; …

 

4.3.  Even Numbers

An even number is an integer that can be divided by 2.

Example of even numbers: 2; 4; 6; 8; 10; …
