Review:
In this imaginative and witty tale, a boy named Robert meets the Number Devil in his dreams,
who introduces him to the magic of numbers — from primes and infinity to Fibonacci and
factorials. With vivid illustrations and storytelling, this book makes abstract math concepts feel
fun and friendly. A perfect blend of fiction and math, it gently opens young minds to the wonder
of mathematical thinking.
