What book / resource can you recommend to draw knowledge in mathematics (grades 10-11 - tower)?

Question

Mathematics

At one time, for various reasons, I forgot mathematics, now I myself sometimes want to understand what is written in various smart things, and sometimes I need it at work. Can you recommend a good book to improve your knowledge? I would like to refresh the material of grades 10-11 and in more depth already the tower. Ideally, I would like a good book with explanations and problems. Perhaps some Internet resource.
PS Do not offer video materials, seriously, I'm certainly grateful for any help, but experience shows that I haven't watched a single video material yet :)

Answer 1

"I haven't watched a single video material properly yet :)"
And why did you decide that you would finish reading the books?
Take a regular 10-11 grade textbook, google and decide.
