If the sum of 2 and 8 is 10, what is the result of their addition?

• A. 10
• B. 8
• C. 6
• D. 2

Answer: (A)

The sum of 2 and 8 is determined by adding the two numbers together. When you perform the addition, you calculate \(2 + 8\), which equals 10. Therefore, the correct answer reflects this result, affirming that the outcome of adding 2 and 8 together is indeed 10. Understanding basic addition is fundamental, as it lays the groundwork for more advanced arithmetic concepts. In this case, verifying the calculation by counting or using other methods would also lead to the same conclusion, reinforcing the reliability of the addition rule stating that adding two integers yields a new integer that represents their total.
