Question

Which of the following statements shows the inverse property of addition?

Oa+(-a)=0
O a+0= a.
O1a=a
O a+a=2 a

Answer 1

`a+(-a)=0`

Explanation:

Let
`a\in \mathbb R`, that is a be any real number.

The inverse property of addition says that, the sum of a number
`a` and its additive inverse
`-a` gives the identity element of addition which is zero.

That is :

`a+(-a)=0`

We can rewrite this as
`-a+a=0`

From the above options, we have the correct answer to be the first choice
