evaluate
\n" ); document.write( "6 4 7
\n" ); document.write( "4 2 0
\n" ); document.write( "2 6 5
\n" ); document.write( "=====
\n" ); document.write( "= 6*(10) - 4*(20) + 7*(24-4) = 60 - 80 + 140
\n" ); document.write( "= 120 (if you mean the determinant)
\n" ); document.write( "----------------
\n" ); document.write( "I don't know if the 1st one is 60. Might be, might not.
\n" ); document.write( "-----------------------------
\n" ); document.write( "All the elements in the middle column are doubled, so the 1st one is 60.
\n" ); document.write( "
\n" );
