CHECKING. Once you have worked a problem, how do you know if you
arrived at the correct answer? One way is to do the problem over again
from the beginning (and hope that you don't make the same mistake
twice). Another way is to check (verify) your answer by rearranging the
problem and solving the new problem.
For example, when you subtract, you can check your answer (the
difference) by adding the difference to the subtrahend. If your subtraction
was correct, the resulting sum will be the minuend.
Look at this problem:
