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( " \n" ); document.write( "\n" ); document.write( "jon. \n" ); document.write( " |
