AEqual to zero
BThe number itself
CEqual to one
DDouble the number
Answer & Solution
Correct answer: B. The number itself
1. Consider adding zero to any number, such as 11 + 0 or 0 + 42.
2. In both cases, adding zero does not change the value of the other number.
3. The sum of any number and zero is the number itself, which is called the Identity Property of Addition.
4. The sum is not zero, one, or double the number, since none of those describe what actually happens when zero is added.
