I was a member of another forum for a few years and quite enjoyed it there (sadly, they've since closed down), but they weren't into giving my puzzles (ones that I've posted here) much of a try, and so I started looking around.

I tried several sites but couldn't find one that showed much interest in the puzzles, and so I kept looking. I then found MIF - probably from googling "number puzzles" (or something like that), and got enough response to stay.

I wasn't sure early on if I'd last because the maths level here was so high (compared to mine) and I didn't feel I could contribute much, but at the same time I was intrigued to see how my logic puzzles with their low maths-standard content would be received in a higher maths forum like this.

Well, I joined some threads here that hit the spot, and, despite the fact that I didn't quite get the response to my puzzles that I'd expected, I stayed and had some fun on those threads. And despite not being able to join in much on the maths side (because, quite simply, I've got no idea about what's said in most of the maths posts...but still I read a lot of them), I've hung around, learnt some things, used my limited LB skills sometimes, sharpened up on M a fair bit, joked around...etc.

I thought you were going to say, I saw that bobbym guy and said wow what a genius. Unfortunately no one says that. I joined because of JFF a real genius.

Oh, yes: "Wow, what a genius", I thought. "It would be nice to rub cyber-shoulders with him." There...I said it, even though my name is not 'no one'.

I thought you joined so you could draw swords against Ricky. Yes, JFF was special, blessed with a mighty amount of knowledge and experience, and always seemed to have incredibly well-thought-out things to say. I have to say "seemed", for the reason you know.

Ricky decided that for himself. It was never my intention to lock horns with him. He did one very great thing in those discussions that I admire. He never once pulled rank on me. He was a moderator and I was just a member but he argued like we were both the same.

Yes she was very spirited. I think that is what you meant.

**Hi;**

**New Problem!**

**A rectangle is drawn with vertices (0,0),(2131,0),(2131,1871),(0,1871). It is divided into squares of 1 x 1. If a person starts at (2131,1871) and makes his way to (0,0) in a straight line how many squares does he go through?**

**A says) 4000 of course!**

**B says) Nope.**

**C says) I am getting 4001.**

**D says) 10**

**E says) I have just been counting them, now I am stuck.**

**Do you know?**

Initially I thought it may have to do something with line drawing algorithms.

I worked some smaller ones and spotted what hopefully was a pattern. Didn't get the idea of using yours though.

I noticed that a lattice point is reached gcd(m,n) times, then came up with the formula.

I have been working on anonimnystefy's urn gf and series. Came across an answer in a book.

Urn gf, which is it? Not the matrix problem I suppose?

No, the other one where he used a sequnce to describe an urn problem. Wished I could find it...

I believe it is this:

We all were trying to get a closed form. He was going to send it in to Conroy, but he did not understand the solution.
