I am a high school student and I want to get the most rigorous math education available in algebra and geometry. I was thinking the SMSG books from yale univ, but that may be outdated (they use stuff like "truth sets"). How about this plan: Starting of with basic math by lang Algebra by gelfand Lang's geometry/kiselev geometry gelfand trigonometry Gelfand and sullivan's precalculus/"graphs and functions" Is this enough to give me the strongest, most rigorous background in algebra and geometry? Or should I consider the yale univ SMSG books as well? Thanks.
