What's the best approach to learn mathematics from the bottom-up?

Let's assume all I have is some shitty highschool-tier math background knowledge (which is also obsolete for 10 years) how do I go on about learning it all?

I don't only want to simply absorb the knowledge in order to read certain papers but also want to learn why stuff is done the way it is.

Is a historical approach to this good? Should I read myself into the history of mathematics to get a deeper understanding of why math is done the way it is? Or is that a waste of time?

what would you need in order to replace neurons in a brain with synthetic counterparts that aren't prone to decaying over time and can be reprogrammable? i was thinking it'd have to be capable of changing and sitting in the same orientation, so it would have to be an artificial stem cell capable of differentiation so that the static problem of placing it isn't as big of an issue.

but then how much knowledge do we have of the aciton potential and metabolic pathways of a stem cell? can they be replaced with artificial counterparts? is that something which can be stable for a longer period of time than a human neuron? what type of research is needed for this? i'm really keen on whether or not neurological prosthesis is a thing i can study and contribute to in the future.

I don't know any like the ones you posted, but there are some charts and guides (like the one in the pic related which I think I got from the wiki) made by the people here, but I don't have them

I left school in year 10, I was in the top math classes all through school, but I got bullied violently and eventually dropped out.

I've completed a law degree since then because reading and writing is easy enough, but math builds on math builds on math, and I'm missing so much knowledge.

I'm interested in economics and machine learning/statistics, but I can't get close to understanding the papers about them because I don't have any idea what I'm reading.

It makes me feel embarrassed and ashamed as pathetic as that sounds.

Has anyone else here done something like self taught or gone back and learnt it years later somehow? If yes, can you tell me your experience such as how long it took, how you did it, how you found it?

I feel really ashamed/embarrassed that I am no good at math.

Hi /sci/, I'm a normal highschool student and I'm not here to disccus about the best stem. Just wants to know what are your best sources of:

>E-books
>Sci News
>Courses
>Videos
>Software you usually work with (as Mathlab, Mathematica or a CAD program)
>Something you might want to add

Also, post your best stem images

I suggest "Intermediate Algebra" by Johnston, Willis, Lazaris. I used the 6th ed in CC, but you can get the 5th on Amazon for super cheap. Good primer on basic and intermediate algebra, lots of examples, holds you by the hand and explains everything, a few proofs toward the end, and you can easily supplement it with online resources.
Here's one for $1.60 actually:
>http://www.amazon.com/Intermediate-Algebra-Johnston-Willis-Carol/dp/0534143288/ref=sr_1_fkmr0_3?ie=UTF8&qid=1433092397&sr=8-3-fkmr0&keywords=intermediate+algebra+johnston+5th+edition
For a newer 6th ed for $24:
>http://www.amazon.com/C-L-Johnston-Intermediate-Algebra-6th/dp/B00N4IRTI6/ref=sr_1_2?ie=UTF8&qid=1433092371&sr=8-2&keywords=intermediate+algebra+johnston

If you're feeling a bit more adventurous, "Basic Mathematics" by Serge Lang gets recommended on /sci/ boards and physicsforums. I haven't personally read it so won't talk at length about it, but it's written from a mathematician's perspective, so it's more difficult, but gives an excellent well-rounded primer up to precalc.
>http://www.amazon.com/Basic-Mathematics-Serge-Lang/dp/0387967877

After that jump to "Calculus," and "Calculus of Manifolds" by Michael Spivak. "Brief Calculus and Its Applications" + solutions manual by Goldstein, Lay, and Schneider is also good.

Anons that had more experience with these will be able to recommend more books, but they won't come back utill later in the night. Cheers.

Hi, /sci/.
I'm trying to make my own tiered chart of the math types, but I'm not really sure how. What I'd ideally like to do is make something from its most babby mode, like say, "Numbers are symbols, here are the symbols and what they mean, this is positional notation and how it works", to "this is how addition works/subtraction" to "this is how to multiply" to "This is how algebra works" and so on.

Unfortunately, I can't really juggle all these subjects, and the vast majority of them I've never even heard of before. I don't know how to tier them and make them flow in a tree away from the most basic and rudimentary of math subjects, because I've never approached them before.

If you were to make a tiered or treed list of mathematical subjects, ones with fundamentals and laws and rules from which further subjects of math were predicated on, how would you do them?

I never got far beyond pre-algebra and I'm trying to make a clear path for myself to know where I am, where I go from there, where else I can go based on what I know, and where that path will lead me to.
Who knows, it might help other people in the same boat I'm in.

Hi, /sci/
So, I'm an idiot and I'm trying to make some sort of list of fundamentals in math, going from "numbers are symbols" up through the various disciplines of math. Unfortunately, I'm having problems deciding how to.. sort of.. number this. Starting with #0 for "Why Study Mathematics?"
I'm trying to reproduce chart in the form of numbered nodes, but that doesn't really work.. some of these nodes share other nodes with more advanced nodes. It's not a clear flow from the first subject to the last. There are concurrent nodes and even further divisors..
I don't know how to arrange these in a way that puts them from the most basic to the most advanced. Can someone help me?
