Question

(ii) The multiplicative identity for integers is -1.
​

Answer 1

Answer:

No

Step-by-step explanation:

The multiplicative identity property states that any time you multiply an integer by 1, the result, or product, is that original number.

To write out this property using variables, we can say that n×1=n. It doesn't matter if n equals to one, one million or 3.566879. The property always hold true.  

Let us take an integer n=2 then,

2×1=1×2=2

Hence, the multiplicative identity for integers is 1.

Answer 2

Answer:

Zero is the additive identity for whole numbers, integers as well as rational numbers. One is the multiplicative identity for whole numbers, integers as well as rational numbers.
