I've annoyed myself by getting stuck attempting to work out a silly maths problem relating to permutations. It's an extension of the 'how many odd socks do I have to pull out of a drawer before I find a pair' problem. Only my theoretical sock-wearer has three legs. And a penchant for odd socks.

How can I help my 6 1/2 year old son to *get* maths? It hasn't clicked with him at all and I find myself getting frustrated with having to repeat really basic stuff when helping him with his homework. I'm not a maths genius myself and I really don't want to put him off by getting cranky because he's just not getting it. How do I help him get it? [more inside]

I am trying to find some good interactive Maths tutorial software which goes from basic algebra through to Differential Equations and maybe beyond. Can anyone recommend anything with the emphasis on the interactive side - something which can keep me interested so nothing too dry - a nice colorful multimedia approach would be ideal.

I'd like to learn Math. I'm particularly interested in learning trig and calculus. I'm don't need to learn these disciplines for any purpose. I'm just interested. I'm a reasonably bright guy, with a logical mind (I've worked as a programmer), and I'm a good self-learner. I'm not in a rush (don't mind working at this for a few years). What books/resources would you recommend? I should probably go all the way back to Algebra, which is pretty much where I left off in High School years ago.
