This pop-up book is crammed with mechanics that the reader can pull, revolve and slide. These techniques explore and illustrate the properties of simple arithmetic as well as demonstrating how numbers work and how problems are transformed into solutions. This book rescues maths from the terror of exams. It is for everyone from the youngest student to the most gifted adult. The contents include: pull-outs to help solve simultaneous equations and explain Cartesian co-ordinates; moving demonstrations of Pythagoras's theorem and trigonometric angles; a 3-D model of solid polygons; games to explore probability and geometry; and a glossary of mathematical terms.
