Explain the steps used to determine if Andrea's sum is reasonable.
To determine if Andrea's sum is reasonable, you can follow these steps:
1. Calculate the sum independently: First, perform the arithmetic operation that is needed to calculate the sum. This could be addition, subtraction, multiplication, or division, depending on the context. Use the given numbers provided by Andrea.
2. Verify the correctness of the calculation: Double-check your arithmetic. Make sure you applied the correct operation and used the correct numbers. Check your calculation for any errors or mistakes.
3. Compare the calculated sum with Andrea's sum: After obtaining the correct calculated sum, compare it with the sum provided by Andrea. If the two sums match, then Andrea's sum is reasonable. If they do not match, there may be an error in Andrea's calculation.
4. Consider the context and reasonableness of the answer: Even if the calculated sum matches Andrea's sum, you should consider whether the answer is reasonable in the given context. For example, check if the sum falls within expected limits or if it makes sense based on the problem or situation provided.
5. Seek further clarification if needed: If you find a discrepancy between the calculated sum and Andrea's sum, or if the sum seems unreasonable in the given context, you can ask Andrea for clarification. It is always helpful to communicate and discuss the problem to ensure that the sum is accurate and reasonable.
