Question

Which of the following is an example of the additive identity?

a + (–a) = 0

a + 0 = 0

a + 0 = a

Answer 1

Option C is correct

a + 0 = a

Explanation:

Additive identity:

For any real number x,

`x+0 = 0+x = x`

We have to find an example of the additive identity from the given options.

Option A.

a+(-a) = 0

Which does not follow the additive identity.

Option B.

a+0 = 0

which does not follow the additive identity.

Option C.

a+0 = a

this equation follows the additive identity.

Therefore,an example of the additive identity is, a + 0 = a
