The idea of this book is to help build confidence with maths via a series of tests and puzzles. After a gentle warm-up section the puzzles and tests get progressively more challenging over the course of the book. There is a hints section for readers who get stuck as well as a complete set of answers for every test at the back of the book. After the warm-up section there are puzzles and tests on lateral thinking fun with numbers logic puzzles geometrical puzzles and difficult puzzles. Readers will soon become familiar and comfortable with a range of tricks and tests from magic number squares to Fibonacci numbers.
