\n" ); document.write( "\n" ); document.write( "the answer I think is (8*7)/2 = 28 handshakes, but I don't understand it. Why is it 8*7 I know there are 8 people but why the 7? it's confusing me. Wouldn't it be a lot more. Maybe I just don't understand multiplication or something. Please explain what I don't understand about this.\r

Draw a picture of this, using dots arranged uniformly around a circle. Start drawing and counting ALL of the segments that are possible. NONE is to be duplicated.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "A way to handle this without actually using all eight dots (representing people) is to start with just 3 dots, and draw all segments, and count. Then Use 4 dots, draw all segments and count them; 5 dots, and on like this. LOOK FOR THE PATTERN!.....ANALYZE AND LOOK FOR THE PATTERN.....\r
