comment Congruence modulo n where one side is equal to 1
OK thanks, I just found the terminology and formulation used in the book quite confusing.

comment Congruence modulo n where one side is equal to 1
Let me quote the book: Two numbers are said to be congruent modulo n if they both have the same remainder when divided by n. The remainder of a number a when divided by n is also referred to as the remainder of a modulo n, or simply as a modulo n. So as far as I understood it, they're saying that $a^{n-1}$ and $1$ are congruent modulo $n$, which means that they have the same remainder when divided by $n$. So I'm not sure in your answer...

comment Can I keep adding more dimensions to complex numbers?
For R3 you simply define a number j that has the property j^3 =− 1. - isn't that -1?

comment Any natural number is greater than or equal to its product of digits.
@Hawk I misread the question as "lower than or equal to" - sorry!

I don't get this. If a number has 0 as a digit, wont its product of digits also be 0?

How can you loose those? Wow, I really need to research into this...

@EnviousPage, of course, that's why I put it in the quotation signs...

comment How to transform a set of 3D vectors into a 2D plane, from a view point of another 3D vector?
Hmm, AFAIK, the GPU only knows how to render "polys", usually just simple triangles. Every model needs to be tesselated to a few hundred of those. Well, I'll figure the clipping out when I actually start.

Wait, but wouldn't the vectors outside of the frustrum just... Be outside? I mean, I haven't done this yet as I've been busy, so I'm not sure...

@JyrkiLahtonen, OK, noted, but clipping is just making stuff that is far off and stuff that is too close disappear, right? I can do that...

comment What are some books that I should read on 3D mathematics?
Damn, I just spent a lot on some other books so I'm kinda short. I'll see if I can download it somewhere, and if I'll like it, I'll buy it later. Thanks!

Maybe in the American/UK/whathaveyou school system, here I'm a "first grader" all over again. ;) But yeah, that's what I meant.

comment How can I find the derivative of a function that takes in two variables?
Thanks for that link! Although, I usually found it hard to learn from Wikipedia (but that can vary, depending on who wrote the article)...

Hey, thanks for the answer, but I do understand the problem here, I just didn't know how to write it down... I'm sorry, I should have been more accurate. I'll give you a vote up, when I can though :)

comment Can you please explain this simple task with sets to me?
Thanks, really, I do understand absolutely all the math here, I can list the solutions in my head, the problem was to write them down. Well, you solved both anyway, so thank you. Also, shouldn't it be (Z∖{1}), not (Z∖{0})?

comment Can you please explain this simple task with sets to me?
I do know which numbers are supposed to be there, but I can't simply write {..., bla, bla, bla, ...}, so yeah writing that down is the problem.

Nope, N is without 0, and N0 is with 0.
