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.
