document.write( "You're adding not multiplying. When you add pencils to\r\n" );
document.write( "pencils you get pencils, not \"pencils squared\"! So when\r\n" );
document.write( "you add x's to x's you get x's, not x^2's Here's howa;\r\n" );
document.write( "\r\n" );
document.write( "First write a + in front of the 3x and a +1 in front of\r\n" );

document.write( "\r\n" );
document.write( "Then you add +4 and -6.  They have different signs so\r\n" );
