Scoring Rubric:
**[2 points] No, and an appropriate explanation is given or the expression is
evaluated correctly.
*[1 point] No, and the correct order of operations is used to evaluate 2(3)² +
5, but one computational error is made.
*[1 point] One conceptual error is made in evaluating the expression, but the
question is answered appropriately.
*[1 point] Appropriate work is shown, but the question is not answered.
[0 points] No, but no explanation or an inappropriate explanation is given.
[0 points] A zero response is completely incorrect, irrelevant, or incoherent or is
a correct response that was obtained by an obviously incorrect procedure.
