Hello, all! I have recently developed an interest in mathematics, and I was wondering where I should begin. Unfortunately, my grasp on the fundamentals is rudimentary at best, and I'm looking to sharpen what skills I have and develop those I don't. I would like something appropriate for self-teaching. (But if I reach an impediment too great to be overcome alone, I can find help.) The branches (?) I'm targeting are algebra and geometry, though books about trigonometry, calculus, and others are welcome, too, as I would like to at least become comfortable with calculus. Thanks in advance, guys (and gals)!
