Are some areas of maths inherently central and others as more peripheral?
Or is any sense of centrality just a human experience, a cultural artifact arising from:
what has had greater application,
what has been studied more,
what produces a greater sense of the sublime in the human mind?
Are some parts of mathematics inherently a more fundamental description of what is going on in the universe, or is it as silly (or correct?) to talk about maths that way as it would be to talk that way about a classical ballet? [more inside]

Sister just learned she has to take an Algebra II test on Tuesday that covers the whole shebang. She's forgotten (repressed?) most of it. What's her best bet for an Algebra II crash course that will go over all the topics? She's very smart, but not a math person.

Can you recommend a programmer a book that teaches high school maths step by step? I did maths at high scool and I was OK at it. However, fifteen years later, after forgetting almost all the maths I learnt back then, I am diving deep into the theory of programming algorithms (sorting, tree structures, graph algorithms and so forth). I find the programming straight forward, but I am struggling with the theory and proof of algorithmic time and space complexities. I am looking for a book that will cover algebra, logs, limits, inductive proof, matrix manipulation and so forth. [more inside]

Math Help! We're doing a big inventory project in my library this summer and we want to attach weekly prizes to it to help motivate the poor students who have to do all the scanning. Trick is, students do not work the same amount of hours per week, so we would like some way of weighting each student's output so that those that work less feel like they can compete with those who work more while not disadvantaging those with longer hours by requiring them to go insane in order to keep up. How to keep things fair and sane? [more inside]
