Granted, but it was still condescending, and that's all I was trying to point out. When I was called out on it, I specified what I meant. I don't think anybody disagrees that Hower could have been more tactful.
And I can only assume that people who ask for something know what they're getting into. The books I linked to assume a level of mathematical maturity on par with an understanding of linear algebra and possible some abstract algebra as well. The OP can probably judge for him/herself based on the level of understanding of that material how much they really know about math.
Oh well. I just think it's a little pretentious to offer advice where it isn't asked for. The OP didn't ask "do I know what I'm talking about". And he didn't make any claims beyond that he had been doing some self-study... certainly nothing to argue with. I don't disagree with suggesting that self-study may not be the most effectual method of doing things, and that making sure you have a strong grasp of the fundamentals is important, but... anyway, I think you guys see what I'm saying.
