Needs to be Law-of-Five'd.
Pfft. Too easy.
6+3+8=17
(6/3=2)+8=10 (first multiple)
6/8=.75, 7+5+3=15, divided by the 3 (number of digits in the final sequence) = 5
6/.38=15.789473684210526315(repeat) Add those together = 80, divided by 15.789473684210526315 = 5.06666666666666666692 all numbers after decimal added = 119, divided by the 5 in front of the decimal = 23.8.
This is of course a sign that Lulu, and possibly me, are tools of the Illuminati/Chaney/HomelandSecurity(tm)/Starbucks/David Icke, and will hunt down anyone buying this book.
So make sure you give them away quickly!!!
