Answer to Problem 1CR
0 is the additive identity number and 0 is multiplicative identity number.
Explanation of Solution
Additive identity states that when a number is added to zero it will give the same number. Therefore, zero is the additive identity number.
Suppose
Similarly, multiplicative identity states that when a number is multiplied with one it will give that number as product. Therefore, one is the multiplicative identity number.
Suppose
Hence,
0 is the additive identity number and 0 is multiplicative identity number.
