Long before his rise to cult fandom on University Challenge, Bobby Seagull was obsessed with numbers. They were the keys that unlocked the randomness of football results, the beauty of art and the best way to get things done.

In his absorbing book, Bobby tells the story of his life through numbers and shows the incredible ways maths can make sense of the world around us. From magic shows to rap lyrics, from hobbies to outer space, from fitness to food – Bobby’s infectious enthusiasm for numbers will change how you think about almost everything.

Told through fascinating stories and insights from Bobby’s life, and with head-scratching puzzles in every chapter, you’ll never look at numbers the same way again.
