Discovering Mathematics Workbook 3 (2nd Edition)


Discovering Mathematics (2nd Edition) is a series designed for the students in secondary schools and approved by the Ministry of Education, Singapore, for the latest secondary Mathematics syllabus. The series prepares students for the Singapore Cambridge O-Level examinations, and guides students to understand and internalise mathematical concepts and apply them in real-life.

Each workbook is written as a supplement to textbook to give students more practice in applying the concepts learnt. Students may refer to the summary of the important concepts in each chapter of the textbook for a quick review before attempting the questions in the workbook. After completing the exercises, students will not only polish their own analytical skills, but also develop a stronger foundation in Mathematics.

Key features:
