So, here in this question it is said that we have to fill the blank with the term which consists of natural numbers, zero and negative of natural numbers. As we know that the set of positive and negative natural numbers and also including the zero are known to be integers.

Therefore, the integers are the number that consists of natural numbers, zero, and negative of natural numbers.

Now we have to tell what zero is called and for this let us suppose an equation, $ 7 + x = 7 $ , from this we will get the $ x = 0 $ . So from this, we can see that the numbers which when added to a number and when it returns the same number then that property is known to be an additive identity.

Hence, zero is called the additive identity.

Now for the third blank, we have to tell what it will be called as a multiplicative identity. So for this, let us assume an equation as $ 4 \times y = 4 $ and from this we get $ y = 1 $ . Hence, from this example, we can see that the numbers which when multiplied to a number and when it returns the same number then that property is known to be a multiplicative identity.

So, $ 1 $ will be called the multiplicative identity.
