Paul Erdos loved numbers and grew up to be one of the greatest mathematicians in the world. And it all started with a big problem …his nanny. Nanny loved rules. Paul didn’t. So he counted the days until his mama returned. And he kept on counting. He added numbers, subtracted numbers, and discovered that you could go the other way beyond zero. Negative numbers – what a cool concept for a young child!
This book describes the life of a very eccentric mathematician who couldn’t tie his shoes but could find patterns for prime numbers. If you’re not too sure about prime numbers, don’t worry – there’s a great explanation in the story. There are wonderful illustrations of Paul and his college classmates “doing math” around Budapest; they see math in rooftops and steeples. Read the rest of the review at Archimedes Notebook.
