My sixteen year-old brother wants to hop into math. He's covered geometry and algebra 1 +2, as well as trigonometry.
Calculus is the next step, correct?

I'm lurking with interest and I have to teach my son at some point.
>>8595326
yes get stewarts 7E or 8E book or find a pdf of it

Is that something he should focus on for a long while until he moves onto calculus II?

Does he know about exponentials and logarithms? If not he should read a pre-calculus book like Lang's Basic Mathematics.
Otherwise he's ready for calculus. I recommend Keisler's free book Elementary Calculus: An Infinitesimal Approach (https://www.math.wisc.edu/~keisler/calc.html).
Although calculus isn't the only option, he could also start learning linear algebra like with Hefferon's Linear Algebra (http://joshua.smcvt.edu/linearalgebra/) or Treil's LADW (http://www.math.brown.edu/~treil/papers/LADW/LADW.html)
