Preface
These two volumes are intended for students who want to pass 0-Level
mathematics in the modern syllabus. They are particularly suitable for those
who need to follow a thorough revision course, whether at school or as full
time, day-release or evening students at colleges offurther education. Since the
only mathematical knowledge assumed is simple arithmetic, the books are also
suitable for those who need a pass in 0-Level mathematics to improve their
promotion prospects, and are starting the modern syllabus for the first time.
The majority of the exercises are divided into A and B sections. The
questions in the A sections are generally shorter and intended for routine
practice in the techniques appropriate to each part of the text. Longer and
more thought-provoking questions are found in the B sections. Each of the
sixteen chapters ends with a multiple-choice test and a selection of mis
cellaneous examples from past examination papers.
The authors are grateful to Dr Patricia Dauncey, for her helpful criticism of
the manuscript and for working through the exercises. They also wish to thank
the Controller of H.M.S.O. for permissions to use Statistical Abstracts.
The text covers the 'modern' alternative syllabus of each of the major
examining boards, and the authors acknowledge with thanks the permission
given by the boards to quote examination questions. The source of each
question is shown in the text by the following abbreviations

so on. Similarly, 14 is 7 x 2, 21 is 7 x 3, and so 14 and 56= 2X 2 X 2 X 7
21 are both multiples of 7. 126 = 2 X 3 X 3 X 7
The converse of the statement '14 is a multiple of The primes which are factors of all three numbers
