You are required to show your work on each problem on this exam. The following rules apply: Clearly and neatly present and show your work for each problem. Mysterious or unsupported answers will not receive full credit. A correct answer, unsupported by calculations, explanation, or other work will receive no credit; an incorrect answer supported by substantially correct calculations and explanations might still receive partial credit.
