For many students, learning mathematics is like learning a foreign language and it can be difficult for the teacher to explain the meaning of mathematical terms in simple but accurate language. This dictionary overcomes that problem. It defines all the math terms that students in Australian schools are likely to meet, in simple language and without losing accuracy. Definitions are supported and reinforced by diagrams and illustrations. In this third edition, approximately 100 additional terms are defined and the reference section at the back of the book has been updated.
