When I was preparing to apply to grad school ~4 years out of undergrad I spent a lot of time working through the various Math modules on Khan Academy and found it very helpful for getting me back up to speed on the basics. They have some higher-level math content on there too now, I believe.

#12Here are some excellent YouTube playlists for the subjects you mentioned. I have used and can vouch for the high quality of all of them:
Linear Algebra: https://www.youtube.com/playlist?list=PLlXfTHzgMRUKXD88IdzS1...
Probability: https://www.youtube.com/watch?v=KbB0FjPg0mw&list=PL2SOU6wwxB...
Calculus: https://www.youtube.com/user/professorleonard57/playlists
Be sure to work through problems and not just watch lectures, because otherwise you'll forget the content. For example, the linear algebra course has a companion site with problems, and the professor of the probability course wrote an excellent book with problems.

#13I've been doing Khanacademy. Its been fun.

#14I'd love to have enough time to read everything about homotopy type theory / category theory / number theory / cryptography. Heck I'd even want to read the complete Art of Computer Programming from beginning to end. It's so hard to balance this with being productive. Life is too short.

#15I asked this question on reddit a few days ago!
My basis was I wanted something like Charles Petzold's "Code" from 1995 which is the BEST way to understand computers.
The recommended book by far was..."Mathematics: From the Birth of Numbers".

I'm reading Code right now. It really is a fantastic read.

#17Install Anaconda. Start playing with open science data sets. Gain superpowers. Solve big problems. Good luck! https://www.continuum.io/downloads
This might be a slightly better page: https://www.continuum.io/anaconda-overview But, they really don't give enough info about what, where, why. What data? Who is this intended for? Etc.
I think the poster assumed that data science/computational work could provide the mathematical background the OP is looking for.
Because Anaconda is a package of tools that include numpy,scipy (python numerical and scientific computing) and a notebook (a "live editing" utility).
While this might help, I wonder if this is too roundabout a way to learn math.

#18Same boat. I was just going through boxes in my garage and came upon my old college math textbooks and some old exams/homework assignments. It was like gibberish. My plan was just to take a textbook and see if I can just relearn. Probably are better options out there, but I'm clueless. Probably will start with either linear algebra or maybe set theory? Happy to hear other ideas of how people would do this. For me, th…

This can work. I spent a year or so before grad school at work, I brushed up by spending a summer drilling through a Linear Algebra book.
A new thing I have been trying out recently is find an application, find something I am confused by, dig deeper through the layers of mathematics till I uncover the basics of the confusion, then re-learn and work up.
So BFS vs DFS. The latter seems more like up my alley. YMMV

#19I have found http://www.betterexplained.com very fascinating (no affiliation).
The author, a person also interested in programming, comes up with intuitive ways to explain mathematical concepts.

#20Khan academy and youtube in combination are probably better then any of the schooling I originally recieved
