Checking your work |
Checking does not mean doing it again. If you did it again, you did it again, but you did not check.
| • | Check that you answered the question in the problem. |
| • | Check that you used the tools correctly. |
| • | Ask yourself how you feel. If you feel good, you are probably right. If you feel bad, you are probably wrong, and look more carefully. |
| • | Check the numbers and signs separately. |
