( I have absolutely no idea the stuff you were talking about lmao! I'm only 12 years old but i can still probably attempt at some parts. geometry shapes?)

Welcome, Sekky! Impressive study list.

Had a look around your website ... I like your Flashmatics project.

And ... we noticed the "Nullity" story, too and talked about it here: http://www.mathsisfun.com/forum/viewtopic.php?id=5329

We have a wide community here (I like to think of it as a Village smile), so be prepared to enter all kinds of discussions from simple to advanced  to pure opinion.

Why is the message about you, yet the subject is telling people to kneel before me?

wow... Zach got told lol! GO SEKKY! WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!

Anyway I like simple math so i dont have to do anything troublesome lol! i usually like coordinates,
algebra( thats not too advanced but i still can use it)
and probability.

MWAHAHAHAHA ZACH GOT TOLD! MAJOR MAJOR POPULARITY DROP!

sozzy thats really mean of me. Sekky he didnt really mean anything bad. Its just a joke within the speech. He's always like that ^_^ and thats why we all love him! ^_^. poor poor Zach. But then again knowing him he wont like pity ^_^

I'd like to note that "Problem 1" on your website, although very slightly different than my statement, was introduced to Delta by me, which in turn was presented to me by a colleague. I just thought I'd tell you this since you state that you "feel obliged to ask" before posting problems.

Here is the thread:

http://www.mathsisfun.com/forum/viewtopic.php?id=5833

Also, if you haven't solved it yet, you probably never will unless in a hallucinogenic state or if intense insight strikes. I only know one other person who has solved it.

Well the comment I wrote underneath the problem sums up my theory, the function can't possibly be functional, although we could limit it.

Myself and a friend came up with the idea of having a ring whose set was the set of all functions, and whereby function composition was the additive operation (with an automorphic identity, obviously), such that IF we could prove that the group under addition contained an idempotent element (or that we could form a cyclic subgroup) we could find an element such that g is equal to its own inverse, so the problem is finding a monoid operation that distributes over function composition, which isn't easy.

I'd like to see a proof.

Not really...

Firstly, his original attempt at retorting was completely terrible and improper, so I had to change that. I, however, wrote it out more subtly.

How that means I "got told" is beyond me.

Don't let Zach give you that impression. We're generally a nice, likable bunch of wonderful people. Zach's fine as well once you get to know him, he just sometimes gives people bad first impressions.

It certainly is not hostile. There is enough hostility in the world, we don't need it here. We tend to just moderate bad stuff out.

You are very welcome here.

Thanks! So you're a flash user?

I use a product called SwishMax to make Flash (coz I like it's interface better). But it can't do AS3 sad

Interestingly I have recently improved my  Complex Number Calculator

I found the hardest part was (and still is) parsing the user input.

when i made my calculator couple of years ago, i can remember that about 400 lines of code was simply to figure out what the user had put into it, then another 400 odd lines parsing all possible syntax errors, and then another 400 odd lines of code splitting everything into an ordered set of operations on the memory that could then actually be run through to get the answer, and to plot the appropriate graph

In a ring (R, +, ·), (R, +) is an Abelian group. However, function composition is in general not commutative. (Even if (R, +, ·) were a semiring, (R, +) would be a commutative monoid; we cannot escape the commutativity.)

Oh yeah, (R,+) is Abelian....my mistake

So we try it in reverse, make function composition the multiplicative operation and find something over which is distributes, which is never going to happen.
