Hello,
We are excited to have your help in writing solutions for the Math Education Resources. In a few aspects, writing solutions for exam questions for this learning resource differs from just writing an answer key for yourself or your class after the exam. The main points are summarized below, but the most import difference is that your hints and solutions will be used by students who are using your solutions to learn the subject. Hence we highly value clear and simple step-by-step solutions.
Question statements are stated as closely as possible to their original statements on the exam. When appropriate however, questions statements are suitably modified so as to make sense of the problem. In multipart problems, the common text should be copied to all subparts.
