Looking for highschool algebra textbooks in preparation for the IMO. Picrelated seems good but the editions on the internet are horrid. I would rather avoid spending money.
Before you ask the unnecessary question, I am over 18.
Instead of rambling in this thread about how IMO is trash, and I should get a headstart in becoming a Set Theorist instead, please understand that I just want to have a go at it. I'm not going to win, but you don't participate in every competition with the intent of winning.
