Go to the library and read their math books. I don’t know why the internet is filled with these questions that are always “how do I start doing x?” Just f* do it dude. Nobody is going to be able to or bother to answer anyway. The answers wouldn’t make deep sense to you because they rely on having done it before. Once you’ve started and you’re really stuck and everything you read doesn’t seem to illuminate it, post a question. People will notice you’ve put some work and time in and will be eager to help you.
