You can put this solution on YOUR website!
Yes, whenever you multiply or divide by ANY negative number, the < or > swap around.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You could say the same about =, but of course swapping it, it still looks the same ;-)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "eg 2 < 5 is valid\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "now multiply by 3...
\n" ); document.write( "6 < 15 .. still valid\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "now multiply by -1
\n" ); document.write( "-6 < -15 is not true anymore...-15 is now smaller.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, we need to write
\n" ); document.write( "-6 > -15\r
\n" ); document.write( "
