document.write( "Draw three circles that partially overlap each other; label the circles A, B, and C.  In the center, where all three overlap together, put a 3.  That accounts for the \"3 use all three\".  Then it says that 4 use A and B, but you already have accounted for 3 of those 4 because of the \"3 use all three\" statement; if someone uses all three, then they must use A and B, right?  So 4 minus 3 is 1, put a 1 in the little segment where only A and B overlap.  Similarly, 11 use A and C.  Subtract 3 to get 8, and put 8 in the segment where only A and C overlap.  Now add up 8 plus 3 plus 1 equals 12 which is the number of people who use A and Something Else (maybe just B, maybe just C, and maybe both B and C).  Subtract 12 from the 38 that use A to get 26, the number that use ONLY A.\r<BR>\n" );
