The joy is not so much in achieving the objective, but in the journey. The production of this edition has been a challenge, a feat that both my editor and I acknowledged and embraced manfully. The text was totally reconstructed and realigned to reflect the ordered sequence and new requirements of the latest syllabus, 2016, a syllabus that embraced changes to reflect a new paradigm.
I have strived to maintain the user friendly nature of the text. The chaff has been removed and basically the kernel has been highlighted in all the topics. To this end I take full responsibility for any factual error. Condensation can result in unintended deviation.
This text has been a labour of love and a work in progress. As usual, welcome any constructive criticisms, comments and suggestions that can enhance the quality of the text. It is my hope and expectation that the needs of both teachers and students will be served by this, the fifth edition. Once again I must emphasize that this text is not a substitute for good pedagogical skills. Teaching and the use of the text are complementary. My best wishes to all as you chart your course in life's journey.
