Simple averaging, $\"%28E%5B1%5D%2BE%5B2%5D%2BE%5B3%5D%2BE%5B4%5D%29%2F4=+Average\"$
\n" ); document.write( "Add all $\"highlight%28E%29\"$ xams then divide by 4 to get Average right?
\n" ); document.write( " $\"%2873%2B79%2B81%2BE%5B4%5D%29%2F4=80\"$
\n" ); document.write( " $\"E%5B4%5D=%2880%2A4%29-73-79-81\"$
\n" ); document.write( " $\"E%5B4%5D=87\"$ -------------> should be the final score AT LEAST to have 80 Ave.
\n" ); document.write( "The higher the final score of course(>87) the higher the average.
