But if Agnishom's suggestion number 3 was enforced, if someone had seen someone's post and then they edit it, they wouldn't see it again.

Great to see you back! 3 old members are back in one month!

How do you bump on SE or SO?

AoPS is just a stupid forum.

All other forums I am on allow bumping once per day.

3. An user cannot post in thread unless it is the first post of the thread or the post immediately before is done by an user other than him.

Great idea! But then no one could bump or get others to see their edited post.

Sorry, that diagram wasn't needed.

I am 100% sure, unless there is a law against the book, that the Sullivan books are sold there. However, as for the others and the Sullivan ones, you can get them ordered for cheap prices at abebooks.com

I will email you the links for the books online.

Basic Mathematics by Lang
Elementary and Intermediate Algebra by Sullivan (this is one book - there are two separate books as well but get the book with both of them)
Precalculus by Sullivan
Geometry by Jacobs (1st or 2nd edition)

Go through these books (they are all very cheap - you can get them for under 100 Malaysian Ringgit) and you will have the best mathematics education available. Many of those are also available online - if you want to go through them, I will link it.

Too lazy to write it out in an alternate way? By the way, do you know if there is a name for that?

So? Stefy's statement remains the same.

Do you want to learn the math properly or stupidly (i.e. the way it is taught in schools)?

#364 Re: Maths Teaching Resources » Math Olympaid (OMK - In Malaysia) » 2014-05-27 01:58:07

Really? I skimmed it about a 2 years back and didn't understand most of it.

Sorry, had a hallucination. I was thinking of his number theory book.

I think Tucker and Vilenkin are too complicated for him right now.

That is why he will need MathsisFun and Mathopolis first. Except I would have him learn generating functions before binomials, the Tucker book is the best teaching guide for gf's that I know of.

I agree.

Tucker is used in an honors university introductory course.

Those are 2 great combinatorics books! I suggest the Vilenkin and Tucker book too.

Where is the second book? I only wrote one.

I think Tucker and Vilenkin are too complicated for him right now. So it Niven, but he only needs the first few chapters and the chapters near the middle or end on probability and combinatorial geometry.

#367 Re: Maths Teaching Resources » Math Olympaid (OMK - In Malaysia) » 2014-05-27 01:34:49

For combinatorics, see Mathematics of Choice: Or, How to Count Without Counting by Niven (this is one book).

That is a problem for everyone who is self taught. You might think there are many intermediate books oput there but that is because you have a good education behind you. I found the jump from lower to advanced extremely difficult.

I am completely self-taught as well. I learned all high school mathematics by myself before coming to university, learned calculus, real analysis, complex analysis, linear algebra etc before covering it in university etc.

#369 Re: Maths Teaching Resources » Math Olympaid (OMK - In Malaysia) » 2014-05-27 01:23:13

Forums are good, but unfortunately there are no good intermediate level online resources. There are good ones for lower level (e.g. Mathisfun) and for university (e.g. MIT OCW). Nothing in between,

Sure.

All I said was another word for boastful.

Ah, now I get why it was censored.
