These *Skill Review Certificates* review fundamental
algebra skills in a bright and visual way. The make good "reference
tools" when doing homework or studying. Some tell me they can
visualize theses colorful handouts when they take quizzes and tests. These
printable, downloadable files are all .pdf's -- you will need __
Acrobat Reader__ to view them.

**
Exponent Expert. ** Working with exponents is a fundamental
skill. Let's make sure we all feel comfortable, confident, and can
accurately work with them.

**
Polynomial Ph.D. **The sum of terms raised to exponents are
important "building blocks" to many algebraic concepts. Let's review
the basics.

**
Strategic Factorer.** When we work with numbers and fractions,
factoring is a key skill. It is also the key to working with
polynomials.

**Really Good
at Rational Expressions. ** When we write fractions that contain
polynomials in the numerator and denominator, they are called *
rational expressions*. Here's a simple review.

**Fully
Competent: Complex Fractions. ** Not all fractions have simple
numerators and denominators. When we have fractions made up of
fractions, they are called complex fractions. Sound complex? Don't
worry, here are some suggestions to make them easy to work with.

**Linear
Equations.** Let's look at how we can model and predict with
mathematical statements and draw those statements as graphs.

**Systems of
Linear Equations. ** Many phenomena can be models with linear
equations. A system of equations contains more than 1; a solution to
the system has to also be a solution to each equation. Let's review how
it works.

**Rockin' at
Radicals. ** Let's review how to work with radicals and roots.

**Quintessential
Quadratics.** Obviously, we cannot represent everything with a
linear equations, equations without variables. Quadratic equations are
important forms that are used to model many situations.

**Parabolas.** Often
we have to write equations for lines that curve. The graph of a
quadratic equation is a special type of curved line called a *
parabola*. These equations have exponents, hence the curve.
Let's look at how this works using quadratic equations.
