Question

What is the additive identity of any whole number?

• A. $0$
• B. $1$
• C. Whole number itself
• D. Negative of the whole number

Answer 1

The correct option is A $0$

$\underset{–}{\text{Additive Identity}}:$

• Additive identity is the value when added to a number, results in the original number.
• When we add $‘‘0"$ to any whole number, we get the same whole number.
• For example, $5+\underset{–}{0}=5.$

Therefore, $‘‘0"$ is the additive identity of any whole number.

$\therefore$ Option (a.) is the correct one.
