A concise introduction to the content and structure of accounting statements and the double entry system that underlies them. This book is intended as a first introduction to the subject and assumes no previous knowledge or experience of accounting. Worked numerical examples are an integral part of the exposition, and exercises (with solutions) are provided. There are also chapters on the interpretation of accounts, on accounting for price changes, and on broader aspects of accounting. The emphasis throughout is on understanding fundamental principles rather than on detailed practical procedures.
