document.write( "which requires that if you type algebra all on one line,\r\n" );

document.write( "subtractions, multiplications, or divisions, you MUST put a\r\n" );

document.write( "a right parenthesis \")\" after it to show where it ends,\r\n" );
document.write( "because when it's typed all on one line it all runs together\r\n" );
document.write( "and you must do that to indicate which terms are parts of\r\n" );
