All natural numbers are integers that start from 1 and end at infinity. All whole numbers are integers that start from 0 and end at infinity. The set of integers is usually represented by the letter "Z". It can also be represented by the letter "J".
Closure property means when you perform an operation on any two numbers in a set, the result is another number in the same set or in simple words the set of numbers is closed for that operation.
Which numbers are not natural and why? The first number, 33, is a natural number. The second number, 23, isn't because it is a fraction. The third, −8, isn't because it's negative.
Irrational numbers are not closed under addition, subtraction, multiplication, and division.

The associative property holds true in case of addition and multiplication of natural numbers i.e. a + ( b + c ) = ( a + b ) + c and a × ( b × c ) = ( a × b ) × c. On the other hand, for subtraction and division of natural numbers, the associative property does not hold true.
Closure Property A natural number is closed under addition and multiplication. This means that adding or multiplying two natural numbers results in a natural number. However, for subtraction and division, natural numbers do not follow closure property. When a and b are two natural numbers, a+b is also a natural number.
The closure property states that if a set of numbers (integers, real numbers, etc.) is closed under some operation (such as addition, subtraction, or multiplication, etc.), then performing that operation on any two numbers in the set results in the element belonging to the set.
In addition, we have proved that even the set of irrationals also is neither open nor closed.
