1.1: Set Notation and Relations
Every field of study seeks a common terminology and symbology. While it is possible to think about a subject without knowing its particular language, it is not possible to communicate with others about that subject without some common frame of reference. Thus we begin with the basic terms and notations of set theory.
Work these exercises to see how well you understand this material. Hints and solutions to some of these exercises are given on the second page. As the course proceeds, new notations and terminology will be introduced as they are needed. Be sure to not plug-and-chug answers to the exercises. These are to aid your understanding, and it will be difficult to pass the exam if you do not take the exercises seriously. While you should not copy others' work, feel free to discuss these exercises with others who are taking this course.
