Which of the following is an example of the additive identity?
a +(-a) = 0
a+0=0
a+0= a

a+0= a

Step-by-step explanation:

we know that

The additive identity property says that if you add a real number to zero or add zero to a real number, then you get the same real number back

so

Let

a > a real number

a+0=0+a=a

therefore

a+0= a
