Math education resources

I am aiming to create extracurricular programming for people of all ages (but I'm particularly focused on teens and adults) to illuminate the neat areas of math that aren't covered in school. (Graph theory, mobius strips, pascal's triangle, things like that.) However, I don't have a very official background in mathematics myself. 1) What resources can I use to teach myself about math in those areas, or math leading up to those areas? 2) What resources are out there for kids/teens/adults to increase their math awareness?

Counting 101 (and beyond)

Our three year old LOVES to say his letters and numbers. When he gets to Z, he triumphantly (and accurately) announces "and that's all the letters!" When he gets to 100 he proudly informs us, "that's all the numbers!" I've tried to tell him about 101, 102, etc., but he does not believe me. He would believe it if a YouTube video or app told him so. Any suggestions? (Yep, I know this is not a big deal. I just like watching the light bulb go on when he realizes just how big the world is.)

What sort of genius do I need to hire, and where can I find them?

I am in the process of trying to create a complex pricing calculator for internal use in our business. I have most of the data, however I am hoping to engage someone on a freelance basis to help me complete the data set, as well as give some expanded detail on how this data (pricing) can change geographically. What specific professions should I be engaging, and where can I find them? More information below the fold. [more inside]

Learning math online

I want to learn math. I signed up for Khan Academy and I like the format a lot. I really like that there are short lessons that I can complete, and that the software automatically checks the answers and lets me continue when I completed a string of 5 good answers in a row (or something similar). I don't like the video explanations though. I'm just not a video person, I learn much better from text. Is there something like Khan Academy where you can do math exercises online but where the explanation is in text?

Seeking advice about teaching maths

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]

What are inter-disciplinary and atypical uses for math MSc?

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]

Why do we have order of operations in arithmetic?

Why do we have order of operations rules in arithmetic instead of just strictly evaluating expressions from left to right (possibly with parenthesis for grouping if we really wanted to change the order)?

iPad math apps for a 10-year-old?

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.

Quantitative finance jobs for a pure mathematician

I'm a pure mathematician with a Ph.D. and I'm currently a visiting professor at a large state university. However, I'm looking to switch gears and get into the quantitative finance field. The problem is that I don't know anything at all about finance. I know that there are companies such as D. E. Shaw that hire mathematicians that don't have financial experience; what other companies should I look at? Is there any general advice you'd give someone in my position? Also, I have my Ph.D. from a well-regarded state school, but I'm not an Ivy-leaguer; does that put me at a disadvantage?

Name this Mathematics Textbook series

Recently, someone described a 10-volume mathematics textbook series to me. The books were written by a single author, an engineer with a name that sounded Greek, and came with full worked solutions to every single problem, making them ideal for self study. Unfortunately, they could not remember its title, and my attempts to find it with Google and Amazon have failed. Has anyone come across this series?
