 If you don't know how
to solve a problem, make an educated guess at the answer. Check your
guess. If you're wrong, use what you've learned in checking your
guess to make a better guess. Continue to guess, check, and modify
until you find the answer.
Solve using
the guess, test, and revise strategy.
