I know how when ?2+?2+?2... =2 (if the sequence is endless.) I understand that this is like .99999999999... = 1 if the sequence is endless. But why so that ?2+?2+?2... All i know is that it works and that if I factorise it back into itself (i.e if we take ?2+?2+?2... and ?2+?2... then they are equal and if one is taken from the other, if one had infinite repetitions and the other had infinite plus one repetitions, then it works that ?2+?2+?2... =2. What is the equation for factorising this?) My email is runescapez@hotmail.com. Please send all help there (rather than on the noticeboard. Thanks!
