How hard it is to learn school and uni level of math from begining in the adulthood?

if you're older than 25 you will have more difficulties but def. possible.

I’m 23, and having a way easier time in the math component of my engineering curriculum than I did at 19. I’m sure there’s a point at which learning math gets harder with age, but it doesn’t seem to be your early adulthood. In my experience, any potential decrease in plasticity has been more than made up for by increased maturity and work ethic. I always fell into the “smart but lazy” archetype as a teenager, so your individual experience may vary, but growing up for a few years seems to have fixed more problems than it’s caused.

I am 35 and still learning, it is as hard for me as it was when I was a child. But I am an autist and have a mind of 14 years old.

Ignore this tard who obviously believes the myth that if you havent done anything in maths by 25 then you arent going to. You can achieve anything you put your mind and enough effort into. Age is not the major factor but access to resources, hence why it is often easier at school because you are being spoon fed the necessary skills. A firm grasp of preuniversity maths and further mathematics courses are easy to attain, uni is eeeeeh a bit harder and specalised. What uni level mathematics?

i'm pretty sure he denies the implication that once you're over a certain age and your brains stops growing means that you automatically become senile and unable to learn anything

if you have a foundation, it's easy, but learning a completely new concept is harder after 25 or so.

School math are easy, I would even skip them.

You will have a rough time at the beginning with uni level of math because notation is a bit difficult thing to get into, but defo possible, just give it some time.

Not only can you do it, it's easier because you're less retarded than when you were a child.

The process will make you will feel much more drained than a child though.

Start right now:
We know how to count: 1, 2, 3, 4, etc.
For every $a$ , $b$ , $c$ $\in\mathbb{R}$ :
$(a+b)+c=a+(b+c)$ .
$(ab)c=a(bc)$ .
$a+b=b+a$ .
$ab=ba$ .
$a(b+c)=ab+ac$ .
There exists $\mathit{0}$ such that for every $a\in\mathbb{R}$ :
$a+\textit{0}=a$ .
There exists $\mathit{1}$ such that for every $a\in \mathbb{R}$ :
$\textit{1}a=a$ .
For every $x\in\mathbb{R}$ there exists $y\in\mathbb{R}$ such that:
$x+y=\mathit{0}$ .
For every $x \in\mathbb{R}^{\times}$ there exists $y\in \mathbb{R}^{\times}$ such that:
$xy=\mathit{1}$ .
$\textit{0}\not\in\mathbb{R}^{+}$
For every $a\in\mathbb{R}$ either $a\in\mathbb{R}^{+}$ or $-a\in\mathbb{R}^{+}$ , but not both.
For every $a,b\in\mathbb{R}^{+}$ :
$a+b\in\mathbb{R}^{+}$ .
$ab\in\mathbb{R}^{+}$ .

For $a_{n}$ , $a_{k}\in\mathbb{R}$ and $N, M$ counting numbers.
As definitions: $\sum_{n=1}^{0}a_{n}=\textit{0}$ , $\sum_{n=1}^{1}a_{n}=a_{1}$ and
$\sum_{n=1}^{N+1}a_{n}=\left(\sum_{n=1}^{N}a_{n}\right)+a_{N+1}.$ Also as definitions: $\prod_{n=1}^{0}a_{n}=\textit{1}$ , $\prod_{n=1}^{1}a_{n}=a_{1}$ and $\prod_{n=1}^{N+1}a_{n}=\left(\prod_{n=1}^{N}a_{n}\right)a_{N+1}.$ As theorems:
$\sum_{n=1}^{N+M}a_{n}=\sum_{n=1}^{N}a_{n}+\sum_{n=N+1}^{N+M}a_{n}.$ $\prod_{n=1}^{N+M}a_{n}=\left(\prod_{n=1}^{N}a_{n}\right)\left(\prod_{n=N+1}^{N+M}a_{n}\right).$ For every $\sigma\in\textrm{S}_{N}$ :
$\sum_{n=1}^{N}a_{\sigma(n)}=\sum_{n=1}^{N}a_{n}.$ $\prod_{n=1}^{N}a_{\sigma(n)}=\prod_{n=1}^{N}a_{n}.$ $\left(\sum_{n=1}^{N}a_{n}\right)\left(\sum_{k=1}^{M}b_{k}\right)=\sum_{n, k}a_{n}b_{k}.$

The older you are, the easier math is.
Because you gain confidence as you get older, you gain patience to wade through background material and you refuse to not know things. At the same time you also have the duties of family life and career which interfere with learning if you don't schedule time.

Read Terence Tao's 'Analysis I'. You won't be able to do all of it. When you finish go on youtube and look up the CMU Putnam seminar https://www.youtube.com/watch?v=vGQZjITDft4 go on Wildberger's 2 channels and watch/work through every lecture too.

Impossible, or almost impossible. But not because of your age. You can't learn that level of math without a professor guiding you. It's not so much a problem with learning math itself, but with the way books are written. Books like Rudin's or Spivak's expect you to have some kind of instructor to help you out.

It's pretty easy honestly. You should be able to learn all of HS math in a year or two of full time self study. 'Uni math' is harder to say because it could be construed to encompass all of mathematics, but I'll assume you mean the content of an undergraduate math degree, in which case I'd say 3-5 years of full time self study. That being said, there are areas you'll likely be able to skip over entirely depending on what your goals are. You may not give a fuck about probablilty and combinatorics for example
