Re: Set Theory

You just wrote the sequence of letters "jkhkj."  If you consider this a set then it is a multiset, namely {k,k,j,j,h} with the order being unimportant.  If you consider this a set from classical
set theory corresponding to T/F logic then the duplicates would be eliminated and it would be
equal to {k,j,h} with the order unimportant.  {k,j,h} can be considered the Typeset of the
original multiset {k,k,j,j,h}; that is, T{k,k,j,j,h}={k,j,h} where T is an operator that eliminates
the duplicates from a set leaving one of each type.

That being said, is there a question somehow encoded in your sequence "jkhkj"? hmm

Re: Set Theory

Hi noelevans

I think he might have found the answer to his question and that is why he edited his question. It is not what should generally be done.

Re: Set Theory

Thanks stefy!  I was curious and wanted to give 'em an opportunity to clarify.  But of course the post was from July so I figured I probably wouldn't get a reply from the poster,  postman,  or whatever they are called.  wink

Re: Set Theory

You're right!  Even further back than I thought.  You'd think a mathematician could count to 5 and stop there when supposed to!

Re: Set Theory

It's okay. You just got confused.

Have you tried putting up your signature?

Re: Set Theory

Yeah.  I tried putting something like "Math is a language issue more than a brain issue.  Needs fixin'" but it didn't stick.  I'll try something else a little later.

Thanks!  Have a blessed day!

Re: Set Theory

Hi noelevans;

I have checked your signature and it is of legal content. I do not see why it is not appearing to me in your posts. Perhaps it will after a few more. If not I will contact MIF about it.

Re: Set Theory

Hi bobbym

Novices probably cannot have signatures.

Re: Set Theory

We shall see soon enough. I will wait a bit until he is a member.
