Theory:

The closure property of integers states that while performing any operation such as (addition, subtraction, multiplication) with two or more integers, the result of the operation is also an integer.
The result of multiplication of any two integers is also an integer.
 
If \(a\) and \(b\) are two integers then:
 
(\(a × b\)) is also an integer.
Example:
1. \(5\) and \(4\) are two integers, then (5)×(4)=20 is also an integer.
 
2. \(3\) and \(4\) are two integers, then ((5)×(4))=20 is also an integer.
 
3. \(3\) and \(4\) are two integers, then (\(3 × 4\)) \(= 12\) is also an integer.
