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.

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 ?.

What are x and y? (Remember: when you're asking for help you need to be specific!)

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.
