Answer 2

Answer:

Addition

Commutative property says that changing the order or format of the addition has no effect on the result.

For example: 8+2= 10. And 2+8 is also equal to 10.

Similarly, 5+6=11 and 6+5 is also equal to 11.

Closure Property says that when we add two whole numbers the result is a whole number.

For example- 2+3=5. (5 is a whole number)

8+2=10 (10 is a whole number).

Now coming to subtraction.

Commutative Property- says that when we

subtract two whole numbers the result may or may not be a whole number.

For example: 4-5= -1 (which is not a whole number)

Whereas 7-6=1 (which is a whole number)

Closure Property- states that when we subtract two whole numbers it may or may not give us a whole number.

For example: 2-3=-1 ( which is not a whole number)

3-6=-6 (which again is not a whole number.)

But 22-20=2 (which is a whole number)

It's easy once you understand it.

Hope it helps!
