Modal logic

[u/Remarkable-Range7723]

I want to learn modal logic for philosophical and formal purposes. However, I don't have basic knowledge of it. I haven't studied mathematics since middle school. Thus, I feel very lost and have no idea how to get started! Any advice? Book recommendations & video recommendations would also be appreciated!

You could try Ted Sider's Logic for Philosophy. He has a book sample on his webpage.
