Question

Name the property indicated in the following:
$5+0=0+5=5$

Answer 1

We know that for the set of real numbers, zero is said to be additive identity. It means when any real number is added to zero or zero is added to any real number, the result is that real number itself.

Here, a real number $5$ is added to $0$ or $0$ is added to the real number $5$, the result is that real number itself that is $5$.

Hence, $0$ is the additive identity in the given expression $5+0=0+5=5$.
