Algebra Prequisites
Students should have a good command of college algebra. Specifically, you
should have mastered variables, functions, grouped expressions,
algebraic fractions, polynomials, exponents, logarithms, and uses of
the mathematical constant
e. If you need to review algebra, there
are many good study books and
web sites. One good book is
http://www.amazon.com/ForgottenAlgebraBarbaraLeeBleau/dp/0764120085/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1201146512&sr=81 Forgotten Algebra, Second Edition by Barbara Bleau (Barrons Educational Series, Hauppauge, New
York, 1994). You may skip the following Units in this book:

Note that in statistics one most often uses logarithms to the base
e =2.71828..., and
log x with no base indicated often means log to
the base
e.
A more comprehensive but much more expensive book we also recommend is
Intermediate Algebra by Alan Tussy and R. David Gustafson, Pacific
Grove CA, Brooks/Cole, 1999.
