Types of Odd Numbers
An odd number except 1 is a composite unless it is a prime number. For example, 9 is an odd number and has a divisor.
It is nothing but the sequential order of the odd numbers. For example, 1,3,5,7,9…
Properties of Odd Numbers
Odd + Odd = Even
When two odd numbers are added their sum is an even number. For example,
Here, 1 and 3 are odd numbers but their sum is 4 which is an even number.
Odd - Odd = Even
When an odd number is subtracted from another odd number, the result is an even number. For example,
Here 7,3 , and 1 are odd numbers, and the result is an even number.
Odd x Odd = Odd
The product of two odd numbers is always an odd number. For example,
Here, 5 and 3 are the odd numbers, and the products too are odd numbers.
Odd / Odd = Odd
The division of two odd numbers always results in an odd number. For example,
Here the 5,3 , and 15 are the odd numbers and the result of their division result will also be an odd number.
The key features of an odd number are as follows.
When we divide odd numbers by 2 the remainder should always be 1 .
1 is the first positive odd number in the number line.
