- Problem solving involves a systematic process that includes identifying the problem, generating possible solutions, and selecting the best solution. 
- After obtaining a potential solution, it is important to verify or check the validity to ensure the problem has been effectively and correctly resolved. 
- This evaluation or validation step confirms that the solution works as intended and meets the objectives set during the problem definition. 
- Checking validity helps avoid wrong conclusions and supports making better decisions and improvements. 
So, checking the validity of the result is indeed a vital part of the problem-solving process.
