Solved Example on Additive Identity
Which of the following satisfies the additive identity property?
- A. 7 + 0 = 7
- B. - 4 + 0 = 0
- C. - 9 + 0 = 0
- D. 2 + (- 1) = 1
Correct Answer: A
- Step 1: In Identity property, the sum of the number and zero yields the same number.
- Step 2: Here, 7 + 0 = 7 satisfies the property of additive identity.
