Our problems are mathematically dual: You are rarely understood by anyone and I rarely understand anyone.

Well, even if you make a serious attempt to understand what he posts, you might understand about 10% of what he posts.

I'm amused by the ambiguity in the post.:smile:

Ambiguity? Where?

The antecedents, of course -- you could easily reverse them.

could we add sumdigits(sumdigits(x)+sundigits(y)) = sumdigits(x*y) into the first theory ? I think it works can anyone help prove it ?.

 science_man_88 2010-11-12 20:01

for example 2047 = 23*89

2+4+7=4 mod 9
2+3+8+9 = 4 mod 9
5+8 = 4 mod 9

so the sumdigits for each multiplier 2kp+1 summed together gives the same as the sumdigits for 2^p+1.

 CRGreathouse 2010-11-12 20:03

So... what are x and y?

23 and 89 in this case.
