How do people learn advanced math
2 by hamiltonians | 1 comments on Hacker News.
I have some basic calculus and linear algebra skills but I am hopeless lost at anything more advanced at that. I try to follow along and I get lost. I am trying to follow this but am stuck . This is just calculus. It shouldn't be that hard. https://ift.tt/3qhg9CV How come some people can answer this so easily even though I took college math and cannot? Why is the skill gap so great? I feel like my education failed me big time. Seeing my crypto investments dwindle to zero, I need to learn skills that will pay me money. I thought I would be able to retire off this but nope. So I need to learn skills that will make me employable.
