There are several errors of arithmetic in the beginning of the second-to-last paragraph.
It should read:
"If you used a four-character password, this would be 62x62x62x62, or approximately 14 million password possibilities. If you used five characters in your password, this would give you 62 to the fifth power, or approximately 920 million, password possibilities. If you used a 10-character password, this would give you 62 to the tenth power, or 8.4x1017 (a very big number), possibilities."

The last sentence on the page, which continues on p.308, also contains errors. It should read:
"A five-character password would have 26 to the fifth power, or over 11 million, and a 10-character password would have 26 to the tenth power, or 1.4x1014."
