evaluate the expression
\n" ); document.write( "-|-12|
\n" ); document.write( "

\r\n" );
document.write( "\r\n" );
document.write( "Build that up from the inside out:\r\n" );
document.write( "\r\n" );
document.write( "1.    12 \r\n" );
document.write( "2.   -12 \r\n" );
document.write( "3.  |-12|\r\n" );
document.write( "4. -|-12|\r\n" );
document.write( "\r\n" );
document.write( "That is, we start with \r\n" );
document.write( "\r\n" );
document.write( "1.    12\r\n" );
document.write( "then put on its sign:\r\n" );
document.write( "2.   -12\r\n" );
document.write( "then put the absolute value bars around it:\r\n" );
document.write( "3.  |-12|\r\n" );
document.write( "Finally put the outside negative sign on it:\r\n" );
document.write( "4. -|-12|\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "That is, start with the positive number\r\n" );
document.write( "1.   12\r\n" );
document.write( "So far, the value is 12.\r\n" );
document.write( "\r\n" );
document.write( "Then put on its sign:\r\n" );
document.write( "\r\n" );
document.write( "2.  -12\r\n" );
document.write( "So far, the value is -12.\r\n" );
document.write( "\r\n" );
document.write( "Then put on the absolute value bars\r\n" );
document.write( "\r\n" );
document.write( "3.  |-12|\r\n" );
document.write( "Absolute value bars around a signed\r\n" );
document.write( "number mean to make the sign of the\r\n" );
document.write( "number positive and erase the absolute\r\n" );
document.write( "value bars. \r\n" );
document.write( "So far we have 12.\r\n" );
document.write( "\r\n" );
document.write( "4. Then finally put on the outside negative sign.\r\n" );
document.write( "   -|-12|\r\n" );
document.write( "\r\n" );
document.write( "That is, we put a negative sign onto 12,\r\n" );
