Even and Odd Numbers Part 3

An even number is a number that ends with the digit 0, 2, 4, 6, or 8. It is divisible by 2. For example: 18, 30.

An odd number is a number that ends with the digit 1, 3, 5, 7, or 9. It is not divisible by 2. For example: 21, 35.

 

Properties of even and odd numbers:

 

 even + even = even  odd + odd = even
 even + odd = odd  odd + even = odd
even – even = even odd – odd = even
even – odd = odd odd – even = odd

 

For example:

Consider the addition expression 66 + 6.

Here, the first number 66 ends with 6, which is an even number.
 

So, 66 is even.
 

Similarly, the second number 6 is also an even number.

 

According to the rule:

 

Even + Even = Even
 

So, 66 + 6 is even.
