Question

For any integer $a$, $a+0=$

• A. $1$
• B. $2$
• C. $a$
• D. $0$

Answer 1

Answer: (C)

$a$

The additive identity property says that if you add an integer to zero or add zero to an integer, then you get the same integer back. The number zero is known as the identity element, or the additive identity. For example, for any integer $a$,

$a+0=0+a=a$

Hence, for any integer $a$, $a+0=a$.
