Why is it important to check for the reasonableness of answers?

Checking for the reasonableness of answers is essential in quantitative reasoning because it helps to ensure that the results obtained from calculations are logically sound and make sense within the given context. This verification step acts as a safeguard against errors in computation or understanding. Even if the calculations are performed correctly, if the results contradict known facts or expected outcomes, it can indicate a miscalculation or incorrect application of methods.

Being able to assess the reasonableness of an answer can also highlight the implications of results in real-world situations. For example, if a problem involves calculating expenses and yields an answer that is unreasonably large or small, this discrepancy prompts a reassessment of the process or inputs used. Thus, confirming that results are logical not only enhances the validity of conclusions but also fosters critical thinking and effective problem-solving skills.
