What are some recommended books, online sources, and applications (PC or Android platform) for becoming good at math?
I am specifically looking for books, online resources, and apps that will refresh my knowledge from the beginning of basic math to learning the curriculum of most undergrad math majors.
I initially googled "how do I become good at math?" and I read an article "Five Ways to be Better At Math" which mentioned mathoverflow.net:
"If all else fails, go to some math forums (like Math Overflow) and ask for book recommendations, telling them you want to become good at math and not just pass a required course; give them specific details and they can help find a book perfect for you."
Upon asking my particular question on mathoverflow, I received this answer: "MathOverflow is for questions relevant to research mathematics. You should ask this question on math.stackexchange.com instead. – Qiaochu Yuan 2 mins ago"
Google and Android market has also found some online sources and apps relevant to my query:
"A+ Click Math Skill Test for K-1 K-12"
"Math Workout - the most popular brain training app on Android"
My background is not in mathematics, but it is in the social sciences, specifically, archaeology. My pre-college math curriculum consisted of arithmetic, geometry, algebra, and pre-calculus. In my undergrad I took a course in business math, logic, and statistics. Assessment of understanding in these courses was equivalent to a grade C. I received a bachelors in anthropology in 2009.
I am now in the workforce, gathering experience in my field and deciding where to go from here. As of now, I would like to design my own projects and go into academia. My theoretical orientation is simply geoarchaeology or "using geology to do archaeology." This covers not only geology and archaeology, but anthropology as well, and chemistry, physics, ecology, and mathematics. Grandly speaking, mathematics provides a chain of theoretical models for the natural world, and so I would like to start from there. I have the time and isolation to learn (I'm a field archaeologist who lives in the back country).
