Additive Identity

Additive identity of numbers is a property of numbers that are applied when carrying out addition operations. The property states that when a number is added to zero it will give the same number. “Zero$(0)$” is called the identity element, (also known as additive identity) If we add any number with zero, the resulting number will be the same number. This is true for any real numbers, complex numbers and even for imaginary numbers.

Suppose, $a$ is any real number, then

$a+0=a=0+a$

For example, $80+0=80$, illustrates identity property of addition, where $0$ is the additive identity.
