Problem of the Day 7/13/11

A book has 125 pages. How many times does the digit '1' appear in the page numbers of the book?
39
 
45
 
59
 
54           
                                                
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    Answer: 59. I counted every number including
 1 and 125 that included the number 1. I added my total together and got 59.
