Umm its quite possible that they all used a fairly similiar and incorrect method for instance to EXTREMELY dumb it down, slightly out of context but Mayans.... 20+12=2012 some other guys, follow simple "logic" and reason 20+12= 2012 and so on and so on, just because a few people got a similiar answer doesnt mean they are right, on a test if a teacher says read the instructions before u write anything and 90% of the class writes first are they right?> so umm stfu? 1luv.
