\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hopefully it is fairly obvious that we have the following equations when looking at each column separately
\n" ); document.write( "A+280 = 500
\n" ); document.write( "B+320 = 500
\n" ); document.write( "C+D = 1000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We also have these three equations when focusing on the rows separately
\n" ); document.write( "A+B = C
\n" ); document.write( "280+320 = D
\n" ); document.write( "500+500 = 1000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Another equation that can be formed is this
\n" ); document.write( "A+B+280+320 = 1000
\n" ); document.write( "which represents adding up the inner 2x2 block of values to get the grand total
