  1. A calculator isn't going to help you on 2^200 -- it's going to give you a rough approximation, but not (for instance) the last digit.

     

    Most often, in AoPS, if there's something ridiculous to work out, there's another way to do it. So 2^200 might be in a fraction that can be simplified, or the question might be what the last digit is (and not the whole number). DS did Counting & Probability and Number Theory mostly without a calculator, although once he had simplified a C&P problem sometimes I'd let him use the calculator at that point.

     

    My rule is always (always!) to set up and simplify the problem before deciding whether a calculator is needed. More often than not you can do it by hand once you know what you're doing.

     

    That wasn't the exact example, just saying I have seen it a couple of times in the Intermediate Algebra. I think one time was graphing and asymptotes and an approximation was what was wanted.

  2. The book says in the How to use this book section: "Chapters 17 through 20: These chapters are primarily intended for those students preparing for mathematics competitions, or for those who want to pursue more advanced study in the subjects of these chapters."

     

    A comparison with the content of more traditional algebra 2 programs such as Lial's would yield the same conclusion.

     

    Thank you. I knew I had seen it somewhere, but I couldn't find it on their website. I didn't even think to look in the book.

  3. You can construct a progression that mimics the content of typical high school courses by counting the respective material:

    Algebra 1 (=chapters 1-13 of Intro to Algebra)

    Geometry (=all of Intro to geometry)

    Algebra 2 (= chapters 14-22 of Intro, 1-4 of Intermediate which is review, 5-16 of Intermediate; ch 17-20 is competition math and can be omitted))

    Precalculus

    Calculus

     

    This puts you with calc in senior year if you start algebra in 8th.

     

    To th bolded; is this on their website or something you know from looking at other Algebra 2 scope and sequences?

  4. The Principles of Riding is a really good handbook for dressage, but might be a little tricky to understand at first. Cross-Train Your Horse and Lessons with Lendon are both good dressage books that are a bit more beginner friendly.

     

    For jumping Hunter Seat Equitation by George Morris is very good. Oh, and the 101 xxxxx Exercises books are very good too.

     

    Also, I agree that British horse magazines are great.:001_smile:
