Step-by-step explanation:

What is an additive identity?

Additive Identity : It is the number which when added to another number gives you the number itself. Look at the following Examples. Here we find that adding a 0 to the whole number 19 and 1345 does not change the value of the whole number. If a is a whole number then a + 0 = 0 + a = a. For every whole number a, a + 0 = 0 + a = a.
