Im with ya Prometheus. I've actually tabulated several mathimatical factors in a dream, and the results varied in result to my Lucid Level. Im going to tell you based on my experience I haven't been successful at all with basic mathimatical problems let alone more complex intergers Numbers in a dream changes quite often not only that, your focal point is shorten. Remember even in Lucid Dreaming Logic is not on our side So mixing around with lots of complexed numbers in an LD you are sure to lose focus and drift back into normal dreaming mode. Math has always been my favorite subject, I mean no matter what you will always come with one answer (being the right answer that is) there is no if's or maybes about it it's either a right answer or wrong one.
