## DON'T PANIC!

I will try to keep the math to a minimum, but as I said in class, if I am
the only one dealing with numbers, you'll all shut off when you see them,
instead of using them as tools. I especially want you to have a good
grasp of scientific notation, because I will be using it extensively.
I will *not* be asking detailed math-type
questions on the quizzes or exams, and will try to make clear what math skills
might be useful.
A astronomy-oriented units/scientific notation website is found
here.

A Scientific Notation reference with practice problems is
here

Through a Google search I found a metric system reference that is reasonable
(some information is in Appendix A of your textbook):
The International
System of Units: A guide for teachers, students and professionals

I also found a link that should help you with any Basic Math Anxiety
(although I will try to go over in class things that you will need/have not
understood). This has sections on both Scientific Notation and the Metric Syste
m: Basic Math Concepts and Fundamentals

This link doesn't seem to cover
the metric system *per se*, but has a section on Scientific Notation
and another on Ratios under the Algebra section. I didn't come up with
the name: Math for
