Best math apps/games for middle schooler
My bright almost-8th-grader is struggling with math basics, and I know that a big part of it is that back in 3rd/4th grade, they stopped drilling the multiplication table as part of the general curriculum. So that fundamental knowledge is missing for a lot of kids :( More under the fold... [more inside]
Okay so what do math majors do with their lives?
I, a person who studied art and media in college, have somehow raised a child who enjoys the hell out of math. As the end of his freshman year of college approaches, he's told me he plans to declare a math major. I'm certainly not against it, but it's so far from what I know that I don't understand it at all. So what do mathy people do when they leave college? He's pretty money-oriented, so I don't think "teaching math" will be something he aims for.
What mathematical techniques came after calculus?
I was reading this article about Nobel prize-winning physicist Richard Feynman, and I came upon an interesting quote. I hope that the quote can be explained to me by someone with a background in math and/or physics. [more inside]
I'd like to read/do some recreational math. Recommend a book
I'd like to read about and do some some recreational math. Like puzzles and stuff like that. I enjoyed the Euclid game very much. I'm leaving this pretty broad, but basically I'd mostly like to DO, but it's ok if there's some reading/learning stuff in between the doing. But I'm not looking for a primarily reading book.

Seeking a math-related article about strange infinite series
My Google-foo is failing me. About a month ago, I started reading a very interesting article about a topic in mathematics. I read only the first few paragraphs before I got distracted by something. Now I want to finish the article, but I can't find it. [more inside]
Please help me do math good again
I used to know a lot of math. That was well over a decade ago. I haven't used it since, and now I'm in a position where I need it again. Is there an online course or a textbook (or a couple textbooks) that will take me on a speed-run from pre-calc to differential equations/linear algebra? With exercises, and the exercises have worked-out answers? [more inside]
Help me figure out what's up with this probability question
Someone posted a probability question on Mastodon: "A, B and C toot the truth with a probability of 1/3 and lie with a probability of 2/3. A makes a toot and B toots an observation on whether or not A was tooting the truth or not. C toots that B confirmed A was truthful. What is the actual probability that A's toot was truthful?" Either I made it more complicated than it needs to be, or a lot of other people are wrong, and I suspect the former. Help me get to the bottom of this! [more inside]
Simple explanation of dimensional space
Years ago I read an explanation on how to think simply about dimensions from the 5th and higher. I'm trying to find it again, or the theory which describes it. [more inside]
What is new in your field?
I want to know what the new areas of research, or new discoveries, are in your field. Things such as CRISPR in biology. I'm interested in all fields, not just the sciences, but I'm especially interested in math and sciences.
I also want to know where to go to hear more news about new discoveries. I read Quanta Magazine occasionally. Where else should I be looking? I want to be reading accurate sources, both shorter sources and ones that go more into depth.
Public librarian seeks statistics input
What information and statistical tests do I use to find out if moving biographies to their own special display actually increased their popularity? I want to take a rigorous approach that includes confidence levels. [more inside]
Career question: museum and math edition
I'm about to graduate with a master's in museum studies. I'm doing a master's project on lesson plans highlighting the math within art pieces at a specific museum. My undergraduate background is not math, but I've become interested in learning more math. [more inside]
Can p → q |- ¬p ∨ q in intuitionistic logic?
Can you prove p → q |- ¬p ∨ q without using the law of the excluded middle or its equivalent? I'm going through a logic book (introductory) and I have an intuition that proving this isn't possible constructively, but I'd like a confirmation.
Searching for a math learning book for children
Sometime within the last two years, I read a positive review of a mathematics book for children of at least kindergarten age that introduced math concepts using the number line as a conceptual focus. I'd appreciate any help in trying to identify this book. [more inside]
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? [more inside]
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?

Online resources for brushing up on basic math skills?
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.
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]
Math-related field trip destinations for Bay Area HS students?

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.
Find standard deviation in Excel, but first develop a labor-saving trick
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]

The heck is a modular form?
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.
Teach myself Math virtually for the first time.
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]

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?
