THE FIFTH-GRADER SOLUTION:
\n" ); document.write( "There are \"9\" pages with page number < 10,
\n" ); document.write( "and it takes only \"1\" digit/character to print each page number for those pages,
\n" ); document.write( "for a total of \"9%2A1=9\" digits/characters to number those pages.
\n" ); document.write( "There are \"99\" numbers less than \"100\", so there will be
\n" ); document.write( "\"99\" pages with one-digit or two-digit page numbers.
\n" ); document.write( "Nine \"%289%29\" of those pages have one-digit numbers, but the remaining
\n" ); document.write( "\"99-9=90\" of those pages have two-digit page numbers.
\n" ); document.write( "As it takes \"2\" digits/characters to print the each page number for those pages,
\n" ); document.write( "\"90%2A2=180\" digits/characters will be used to number the pages with two-digit numbers.
\n" ); document.write( "So far, to number pages 1 through 99, we have used \"9%2B180=189\" digits/characters .
\n" ); document.write( "For most books, after page 99, all the other pages have 3-digit numbers,
\n" ); document.write( "and it takes \"3\" digits/characters to print the each page number for those pages.
\n" ); document.write( "If the book has \"x\" pages, there will be \"99\" pages with one-digit or two-digit page numbers.
\n" ); document.write( "If \"x%3C1000\" , the remaining \"x-99\" pages will have 3-digit page numbers, and we have \"927-189=738\" digits/characters left to print the 3-digit page numbers on those pages.
\n" ); document.write( "At 3 digits per page, we can number \"738%2F3=246\" such pages.
\n" ); document.write( "After that we will have numbered all \"9%2B180%2B246=highlight%28345%29\" pages of the book.
