Description 



Identity for Addition: A number that can be added to any second number without changing the second number. 
Identity for addition is 0 (zero) since adding zero to any number will give the number itself. In other words, 0 + a = a + 0 = a.
Examples
0 + 5 = 5 + 0 = 5 1 + 0 = 0 + 1 = 1 0 + (3) = (3) + 0 = 3
