Re: quick logic question

Hi;

I would agree but let's wait for more input.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

Re: quick logic question

Yeah, I would think they are both NN.

Re: quick logic question

I'm not sure that's necessarily true. NN could be a woman and, therefore, the mother of "the son of NN". The father of "the son of NN" would then be her husband/spouse/whatever. Then the son of the father of NN would be NN's brother and, therefore, the uncle of "the son of NN" and the brother-in-law of "the father of the son of NN".

Presumably the use of the word "the" excludes the other possibility that "the father of NN" had many sons, and - therefore - one of them was NN's brothers.

Re: quick logic question

I don't think the problem was meant to be that complicated lol But it's good to try, and like bobbym said, wait for more people to answer.

Hi;

Au101 brings up some possibilities I did not think of and has a point.
