You can put this solution on YOUR website!
In general, |x| = -x when x < 0. For example, |-2| = -(-2) = 2\r

\n" ); document.write( "\n" ); document.write( "So if a+b < 0, then |a+b| = -(a+b) = -a-b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, |a+b| = -a-b when a+b is negative\r
