Question

Fill.in the blanks
1. Integer _____ is the identity under addition ​

Answer 1

Answer:

The additive identity of any integer a is a number b which when added with a, leaves it unchanged, i.e. b is called as the additive identity of any integer a if a + b = a. Now, when we add 0 with any of the integers a we get a + 0 = a = 0 + a So, 0 is the additive identity for integers.
