You can put this solution on YOUR website!
I'll do one and you can do the rest the same way.
\n" ); document.write( "Look at factors of 10 and calculate the sum.
\n" ); document.write( "\"10\",\"1\"=\"11\"
\n" ); document.write( "\"5\",\"2\" =\"7\"
\n" ); document.write( "\"-2\",\"-5\"=\"-7\"
\n" ); document.write( "\"-10\",\"-1\"=\"-11\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( "(\"-2\",\"-5\")
\n" ); document.write( "
\n" ); document.write( "
\n" );
