Answer:-

18*13=13*18

Whole numbers are closed under addition and multiplication operation

Remember, whole numbers include zero and all positive numbers.

If we use addition or multiplication, we'll get a number in the whole numbers set, but if we use one of the other two operations we might end up with a negative number or a fraction, which isn't included in the set.

Division by 0 is not defined; dividing by 0 results in infinity, which isn't a number.

1 is the identity for multiplication; if we multiply any number by 1, we'll get that number back.

If 0 is added to a number the sum will remain the same. Hence 0 is called the additive identity in the whole numbers.

Example:- 4+0=4

Good luck.
