Answer 1

True. The number 0 is not the multiplicative identity; instead, the multiplicative identity is 1. The multiplicative identity is the number that, when multiplied by any number, leaves that number unchanged. For example, $a\times 1=a$ for any number $a$. In contrast, multiplying any number by 0 results in 0 (e.g., $a\times 0=0$), which does not satisfy the definition of a multiplicative identity.
