# When doing problems set things out neatly and above

This preview shows pages 4–7. Sign up to view the full content.

When doing problems, set things out neatly and, above all, logically. Make sure your solutions make English sense. The correct answer to a problem is never just a number. If a numerical answer is asked for, the correct answer must include a logical argument as to why the number is correct. Doing problems trains you for the exams. If you are stuck on a problem, ask for help! Doing a problem does not consist of just reading the problem and thinking, "Yeah, I can do this". Solve it and write it up logically. Experience has shown that a person who can't be bothered to write up a problem in a neat and logical manner, probably cannot do the problem or has basic misunderstandings and misconceptions. 4

period: Apr. 10-24 University closed: Mar. 29 (Good Friday) and Apr. 1 (Easter Monday) FINAL NOTES : 1. Be sure to read the introductory motivating example at the beginning of each chapter; they are very short, but prepare you for the rest of the chapter. 2. The “What have we learned” chapter summaries are an excellent study resource! You may find it useful to make photocopies of these pages to annotate and refer to for review and self-testing. 3. Do as many of the exercises as humanly possible, and then do more. A bold prediction: if you do more than 80% of the exercises, your final grade will be more than 80% too! *** END *** 7
