Question

# The number which is the multiplicative identity for integers is

A
0
B
1
C
10
D
1000

Solution

## The correct option is B 1Mulitplicative identity refers to a number which, when multiplied with given a number, results in the given number itself. For example, if the multiplicative identity is x, then the product of x and any number, say a, should be equal to a. i.e., x×a=a  ⇒x=1 Or, we could say that 1 is the multiplicative identity, because the product of any number and 1 is that number itself.Mathematics
