Question

Associative property define 3,542, 10,255, 3,54,210

Answer 1

Answer:

For 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=

9

3

=

3×3

3×1

=

3

1

which is not a natural number

Hence, N/W is not closed under
