quick logic question

Are the father of the son of NN and the son of the father of NN the same person ?

i say yes, and it's NN. Am i right ???

NN                                 Father

Son                                 NN

This how I imagined it. thanks

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.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

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.
