What are some good, free online resources for an adult who needs to brush up on basic math operations such as working with fractions, percentages and ratios? Other than Khan Academy. The more interactive the better.
I'm interested in teaching high school students mathematics through a tutoring agency. I have the required experience in mathematics, but very little in teaching. This doesn't seem to be a massive problem for many tutoring agencies, but I want to know: do you have any specific tips/advice about teaching mathematics? And more broadly, any advice about applying for and going to work for a tutoring agency? [more inside]

I teach math to high schoolers in the San Francisco Bay Area. I'd like to get them out of the classroom on a field trip to a local math-themed destination. Any suggestions? [more inside]
I have just completed my MSc in mathematics in Europe. I do enjoy math, but I spent my uni years feeling like a autodidact hippie marooned on an island full of Mr and Mrs I-Want-A-Good-Job. My main interests revolve around humanities (literature/history/anthropology) and economics (but not finance), and instead of starting a "stable" well-paying career I dream about something inter-disciplinary. I am very open to earning little money and relocating just to do kind of work that engages those skills. What are some random uses of my degree? [more inside]

At the age of 24, I just completed my first year of undergraduate studies at a good public university. I am a strong student with a 4.0 GPA, but I feel that my interests are so broad and varied that I don't know how to narrow down on a specific path of study. Compound these problems with the ubiquitous financial and career concerns of the modern college student, and you have one confused student. How can I resolve this inner turmoil and structure a long-term plan that will bring me (at least some) peace of mind? [more inside]

I'd like book/course suggestions to do a slow gentle study of higher Math by myself. I did a bachelor's degree in Math (and Economics) several years ago by myself as an external course (from the Univ of London and LSE), on the side of a whole lot of other things. I did reasonably well, enjoyed parts of it very much, but I've forgotten most of it now. I taught high school Math for a couple of years after that but now work in a totally different field (communication design). I love my work, but miss the brainwork Math required. I'd also like to slowly internalise more Math vocabulary and the structure of the subject, which didn't happen during my Bachelors. [more inside]
Dropped out of school several years ago, drifted for a bit, but now I want to return and get AT LEAST a BS in mathematics. What sources are there for someone returning to school? Should I bite the bullet and pay for college counseling, or are there good free resources I'm missing? [more inside]
I have a series of physical data with a fairly straightforward property: it follows a path in space. If I plot a bunch of successive (x, y) values from the data, they follow a curving, looping line rather than randomly jumping all over the plot. More formally, if I have a point (x[t], y[t]) at time t and (x[t+1], y[t+1]) at time t+1, there is an upper limit on the distance between these two points (and this limit is small relative to the overall variation in the data). Is there a well-defined technical term for this property? [more inside]

I plan on applying to graduate mathematics programs for the 2014-2015 school year and I'm starting to get a little nervous about my chances at landing a spot in a funded program. My major concern is that I have absolutely zero research experience from my undergrad years, and am having trouble focusing in on what kind of work I would be interested in anyways, and I don't know where to start! And the research papers that do seem interesting to me are so specialized, I have trouble understanding them! [more inside]

I'm learning to accessorize! I'd like to find some little mathematics-related accessories, kind of like the women's equivalent to a (relatively subtle) mathematics tie or cufflinks, that are work (think secondary school educator) appropriate. Simple and relatively understated is preferred. I'm also interested in clothing that would be work-place appropriate (not t-shirts!). I had a lot of fun with my regex skirt from XKCD a few years ago.

My son is 10 years old and going into 5th grade in the fall (but he usually does 6th grade math). He likes Stack the States, and we're looking for a math app with similar appeal. We already have Sushi Monster and his younger sister loves it, but I'd like something more challenging for him.
Help me with statistics and Excel. Especially help me if you know any labor saving methods. I want the median, mean and standard deviation for the average price of all items sold, but my spreadsheet-full-of-data doesn't tell me the price of each sale -- just the average price per store, and the number sold at that store. Something like this: [more inside]

For all we know, some mathematical truths might be unknowable. E.g., for all we know Goldbach's conjecture (or its negation) is this way. Yet, if there are unknowable mathematical truths, why might this be? Here are some initial considerations/hacks in the dark: (a) Presumably any computing device would have a finite number of parts. Maybe this would limit its processing power in some relevant way; (b) maybe some of the proofs are too long.

For a work assignment, I need to come by a conceptual understanding of modular forms that's light on jargon and, ahem, actual math. If such a thing is possible.
My son is now 15 months old, and I would like for him to have the best possible mathematics education. What should I be doing now and what sort of long-term plan should I have in order to help him both to learn and to love mathematics? (He doesn't have to be a mathematician when he grows up, but really knowing mathematics is non-negotiable.) [more inside]
I'm a 21 year old college senior liberal arts major who has managed to slide by in school (and life) without ever really learning math beyond a middle school/very early high school level. For no reason in particular, I've decided that I want to get serious about bettering myself in the math department. How can I teach myself the academic math skills I missed out on? [more inside]

Economics Mathematics: I have a Maths degree but lately I've become interested in Economics (Microeconomics and Macroeconomics) and have been reading some textbooks and classic texts and doing some online lecture courses on Economics. But find many of that the "handwaving" graphical "proofs" of economic theories lack a sense of mathematical robustness. Do more thorough mathematics for these ideas exist? Where can I find them?

I have a very strong background in humanities but I've completed three-year undergraduate course in math. Though I passed it without trouble, I feel like traditional textbooks didn't teach make me understand a lot. What are best math resources (books, but not necessarily) that instead of trying to look like PM read more like literature or work on your intuition and talk about big picture implications instead? Something like Godel, Escher, Bach for various areas of mathematics. [more inside]
