Question: which property is this: 6 + (−6) = 0?

6 + (−6) = 0

Look at both sides.

A number plus its opposite is 0.

a number plus its opposite is 0

So it is the inverse property of addition.

= inverse property of addition

Let's check: work out both sides.

The left side is 0.

The right side is 0.

Both the same.

So the answer is right!

6 + (−6) = 0, 0 = 0

Let's look back.

First: compare the two sides.

Last: check.
