Additive identity of matrix ::
In ordinary arithmetic 0 (zero) is
called………
a) additive identity
b) identity inverse
c) both a and b
d) none of these
Explanation:In ordinary arithmetic 0 (zero) is called additive identity because when 0 is added to any real number or when any real number is added to 0, the value of the number does not change. For example 0+5=5
