Philip Carter & Ken Russell 
The Complete Book of Fun Maths 
250 Confidence-boosting Tricks, Tests and Puzzles

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.
