Number Freak

Was at my local library. Checked out Number Freak by Derrick Niederman. Some number facts I know now:

• All odd numbers have the letter e, making 2 the only prime number without "e".
• Five queens are sufficient to attack any square on a chessboard.
• You can move a knight 35 times without having it to cross its own path on a chessboard.
• The number one has too many special properties for its own good.

And many more....

Also saw Rurouni Kenshin there. But they only have book 4 and 6. Not a single book one in the entire system. What a letdown....
