The numbers must be greater than
\n" ); document.write( "or equal to
\n" ); document.write( "\"+5000000+\"
\n" ); document.write( "---------------
\n" ); document.write( "The largest 7-digit number is:
\n" ); document.write( "\"+9999999+\"
\n" ); document.write( "--------------
\n" ); document.write( "Going from the lowest to the highest,
\n" ); document.write( "I have:
\n" ); document.write( "EOEO ( starts with odd, and ends with even
\n" ); document.write( "So, the evens and odds are the same
\n" ); document.write( "--------------------------------
\n" ); document.write( "\"+9999999+-+5000000+=+4999999+\"
\n" ); document.write( "\"+4999999+%2B+1+=+5000000+\" total 7 - digit
\n" ); document.write( "numbers possible
\n" ); document.write( "\"+5000000%2F2+=+2500000+\"
\n" ); document.write( "There are 2,500,000 possible odd numbers
\n" ); document.write( "----------------
\n" ); document.write( "No number starting with 0, 1, 2, 3, or 4 are allowed,
\n" ); document.write( "since they would be less than 5,000,000
\n" ); document.write( "
\n" ); document.write( "
