The identity element is 0.
In short, the identity is the number that gives you back the original number. The addition identity is 0, since x + 0 = x.
To take this a step further, the multiplication identity is 1, since 1 * x = x.
Since you're dealing with the identity element, you'll soon learn about the inverse. The inverse is the number that gives you the identity. For example, x + (-x) = 0, which is the addition identity. And x * (1/x) = 1, which is the multiplication identity.
Hope that helps with the identity.

An element 'i' is called identity element of an operation '_op_' when the result of the operation of that element 'i' with any randomly picked element 'x' is identical to that element 'x':
x _op_ i = x
In example;
Addition: 1+0=1, 2+0=2, 1025+0=1025 : 0 is the identity element
Subtraction: 1-0=1, 2-0=2, 1025-0=1205 : 0 is the identity element
Multipication: 1*1=1, 2*1=2, 1025*1=1025 : 1 is the identity element
etc for every operation you define.

It is 0 since for any x , x + 0 = x which defines unity for the operation of addition
