Henry Dudeney's fantastic book Amusements in Mathematics (available for free download) was published in 1917. The book is a brilliant collection of over 400 brainteasers - fun for nerds! Every puzzle presents a challenge; answers are provided - solutions are not. In my folder, I still have a bank of puzzles I cannot solve!
Puzzle 114 describes Curious Numbers; in this feature I wish to discuss this puzzle and generalise the idea to extend the challenge and curiosity.
But first - what are curious numbers - I looked at Google Search and they directed me to the Penguin Dictionary of Curious & Interesting Numbers. It seems there is a plethora of Curious Numbers - so we need to find a different name - to acknowledge Henry Dudeney, I think Dude numbers is a good choice (I didn't like the other option of Dud numbers!).
Puzzle 114 is described in slide 1:
I hope you have enjoyed reading this blog. I am amazed at the genius of Henry Dudeney who had collected a fantastic range of puzzles.
