Self-study High School Math Textbooks?

I'm new to this website so I apologize in advance if what I'm going to ask isn't meant to be posted here.

A bit of background though: I haven't been to school in 6 years and the last level I've graduated was Grade 7 due to financial problems, as well as my mom frequently being in and out of the hospital. I am now 18 and I wish to go to college as soon as I can, but I need to be caught up on all the math I've missed (I have been studying these past few years with what's available on the internet, but I don't think it's enough).

So my question is, are there any good, easy to understand, high school math books suited for my situation? I learn better with a teacher who can explain the lesson, but since I don't have one I'd prefer books that aren't too difficult, but at the same time provide everything necessary for high school level math and more. I used to be a bright student so I'm sure I can do this on my own with the right material.

Again, if this question isn't meant to be on this site I'd be more than willing to delete it asap! That's all. Thank you for reading. :)

Solution 1:

You can start Higher Algebra by Hall and Knight. Elementary Number Theory by David Burton. (Great for theory, might wanna do Justin Stevens) Circles by Dimitri would be good for beginners. Books by Titu Andreescu are really nice for some advanced prep.

These books are great for Olympiad level preparation.

Solution 2:

Books by Bernard Child, SL Loney are awesome. Do try problems in calculus of one variable by IA Maron. Thomas's Calculus is alse good for in-depth knowledge. Problems in mathematics is good for it's problems (there are too many of them).

Best of luck for your studies.
