Directions:
Solve as many as you can of the problems and list your solutions on this
sheet of paper.
On separate sheets, in an organized way, show how
you solved the problems. You will be
awarded
full credit for a complete
correct answer which is adequately supported by mathematical reasoning.
You can receive half credit for correct answers
which are the result of guesses, conjectures or
incomplete solutions. Included as incomplete solutions are
solutions that list some, but not all,
solutions when the problem asks for
solutions of equations. The decisions of
the graders are final.
and clarity. Your answers and solutions must be postmarked
