You can put this solution on YOUR website!
the mean of a set of numbers means you add all
\n" ); document.write( "the numbers together and divide the sum by the
\n" ); document.write( "amount of numbers you added together.\r
\n" ); document.write( "\n" ); document.write( "-9+(-7)=-16
\n" ); document.write( "-16+3=-13
\n" ); document.write( "-13+5=-8
\n" ); document.write( "-8+6=-2
\n" ); document.write( "-2+20=18\r
\n" ); document.write( "\n" ); document.write( "now divide the sum by 6
\n" ); document.write( "18/6=3
\n" ); document.write( "so the mean is 3.
