evaluate the determinant (3by3)
\n" ); document.write( "

 \r\n" );
document.write( " 1 -1  2\r\n" );
document.write( "-1  2  0\r\n" );
document.write( "-1  3  1\r\n" );
document.write( "

\n" ); document.write( "Det = 1*(2*1 - 3*0) + 1*(-1 - 0) + 2*(-3 + 2)
\n" ); document.write( "= 2 - 1 - 2
\n" ); document.write( "= -1
\n" ); document.write( " \n" ); document.write( "

\n" );
