How to develop in mathematics as an adult?

Question

Mathematics

He studied for a very long time at the university in the specialty of applied mathematics. After graduating from university, I have been working on website development for several years. But then the thought came to me that it would be nice to recall all sorts of mathematical analyzes and probability theories. And so I begin to study data analysis. It takes me at least a year to do this. What resources are there that can help me in this matter and how can I look for tasks without compromising my work?

Answer 1

If you need to repeat starting from school:
stepic.org Basic course of preparation for the OGE in mathematics
If the first courses of the university, then here: Introduction to mathematical analysis
You can enroll directly in the course and go according to plan (matan starts from November 16). But in general, the courses were already in that year, which means you can find their materials.
If you try to turn / generate interest in mathematics, then before the courses, read "The Pleasure of X" by Strogats, an amusing reading, accessible about the essence of such things as integrals, differentials, etc.

Answer 2

Here you just take and teach / repeat 1-2 courses all over again. This is a typical problem if you end up leaving matan areas. Just reading may not work. See test tasks in cs-center or Yandex shad.

Answer 3

https://www.khanacademy.org

Answer 4

It is very strange that a person studying by "prime" asks such a question. It seems that you either did not try hard during your studies, or simply did not go to your specialty. It seems to me that no matter how much time has passed, what happened at the university, all this can be remembered quickly and efficiently. Especially in the key and profile specialty. Since the profile is "applied mathematics", the field of big data analysis and statistics should, in fact, be given to you easier, faster and adaptively.
In fact, you type in any search engine the keywords you want to learn about (be it math analysis, statistics, theory, smo, geometry, tensors, etc.), set the search criteria, and get a bunch of references to literature, for any of which you can easily you can remember and master everything. Oh, it's MATHEMATICS, it's not forgotten!

Answer 5

coursera.org I liked it. I took a couple of Stanford courses to freshen up my luggage, it was interesting to find out what they teach there, and I also improved my English.

Answer 6

It was already mentioned here in the comments, but let me "advertise" again:
https://www.lektorium.tv
is a good resource with a fairly large archive of video lectures, especially good lectures on various sections of mathematics, including those that go beyond university program.
Also, it may be interesting to just go to the NMU website and see what is there, if you have not heard about it.

Answer 7

You can repeat (namely, repeat, and not re-learn) according to the book Bamberg P., Sternberg Sh. Course of mathematics for students of physics. 2 volumes 2006. Available on the Internet.
