Question

Write your own examples for closure property for all numbers (Whole numbers, Integers and Rational numbers) under addition, subtraction, multiplication and division.​

Answer 1

example:- Take two numbers 3 and 9

Now, 3+9=12 which is a natural/whole number

Hence, N/W  is closed under addition.

For subtraction :-

3−9=−6 which is not a natural/whole number i.e. −6∈/N

Hence, N/W is not closed under subtraction.

For multiplication :-

3×9=27 which is a natural number

Hence, N/W is closed under multiplication.

For division:-

3×9=93=3×33×1=31 which is not a natural number

Hence, N/W is not closed under division.
