AKRONG SERIES ELECTIVE MATHEMATICS CHAPTER THREE Binary Operations Introduction In this section, we consider operations on a non- empty set.

A diagram like this is called a Venn diagram, after the English mathematician John Venn — Decimal numbers which neither terminate nor recur are irrational numbers. Show all the members of each set. Finally, my sincere gratitude goes to Mr. Joey Chow C A. Which of the following does not satisfy?

Definition 3. Example 3. Table 3. Three of these properties are commutative operation, associative operation and distributive operations. June Solution a Let Q denote the set of non-zero rational numbers. That is: Compute each of the following, leaving your answers in surd form: Stating the range of values of y for which x is defined.

Determine whether or not the operation is: Determine the inverses of 2 and 3. From Example 3. Hence the identity element is — Similarly the inverse of 0 is 0, the inverse of 1 is 1 and the inverse of 2 is 2.

Each element is the inverse of itself. Exercise 3 c 1. Stating the values of x for which there is no such y. Find the inverse of the real number y. Revision Exercises 3 1. Binary Operations Page BOX M. Providing appropriate solutions to examination problems is of particular importance in the study of mathematics. As a mathematics lecturer, the author has discovered the weaknesses and shortcomings of students in the handling of examination questions. Subsequently, to guide students in answering typical questions in Elective Mathematics as set out in recent examinations, the writer has paid particular attention to those areas of the syllabus, which many students find difficult.

A prominent feature of this book is the inclusion of many examples.
