Which of the following is the result of 7 + 2?

• A. 8
• B. 9
• C. 10
• D. 11

Answer: (C)

When calculating the sum of 7 and 2, you start with the first number, 7, and add the second number, 2, to it. Think of it in terms of counting: if you have 7 objects and you add 2 more objects, you can count one-by-one: 8 (for the first object) and 9 (for the second object). Therefore, the total becomes 9. This addition can also be visualized using number lines, where you can start at 7 and move two places to the right. Each step you take represents the addition of one unit, leading you to the final answer. In this case, the correct result for the operation 7 + 2 is indeed 9.
