We all use numbers every day, yet many people are uncomfortable with them, finding them daunting and difficult.?This book is the antidote to number-phobia. As with learning to swim, you’ll never look back: these are skills you’ll use for the rest of your life. If you think you’re good with numbers already, you’ll soon discover what you’ve been missing: the endless fascination and beauty of numbers, and – at the more practical level – a whole range of techniques and shortcuts you never knew existed.?
