Mathematics (Teach Yourself)

This step-by-step introduction offers clear explanations and worked examples that aim to guide readers to an understanding of essential mathematical concepts and techniques. Beginning with a brief historical outline of the development of mathematics, the book gently steers the reader through the basics of arithmetical processes, algebra and geometry. It then focuses on the electronic calculator, both as a computational aid in financial calculations and other practical uses, and as a useful tool in progressing to more advanced mathematics. Thus, problems involving percentages, profit and loss, and interest calculations are explored and trigonometry is introduced - using the functions available on most modern calculators. Throughout, exercises (with answers) are provided to test and reinforce the reader's understanding of the topic.
