Mr. Stephenson's Hotlinks:
Here's a GREAT site:
What job and salary do you want, what math do you need?
http://www.xpmath.com/careers/jobs.php and http://www.salary.com/salary/layoutscripts/sall_display.asp
Fractions: Get rid of your fear here:
http://www.visualfractions.com/index.htm, http://www.mathleague.com/help/fractions/fractions.htm and http://www.barcodesinc.com/articles/become-an-expert-a-guide-to-fraction-fun.htm
So much of life's math is based on fractions that you need to be able to work with them or be forever handicapped. Some time spent on these sites will go a long way towards curing your fraction phobia.
Powers of 10 in the Cosmos
"View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons."

I just found this one. Looks good.
A great Algebra 1 site for Graphing Linear Equations. Use it to review topics you're having trouble with or want to strengthen. It has interactive tutorial lessons, as well as quizzes and tests.
This is our textbook site. Our textbook is the 1998 version of the two volume set to the left (our text isn't really two volumes, they just break up the chapters into two web pages).
If you explore the links you will find useful stuff; including practice quizzes and tests by lesson or chapter -- with hints and immediate scoring. Great for reviewing. (-> Online Study Tools -> Algebra -> Algebra 1)
This site has some review topics, some Algebra 1 topics, and some topics beyond Algebra 1.
The Math Forum at Drexel University is a good place to find information on any math topic, especially in their archives. In case their archives do not have an answer to your specific question, you can ask Dr. Math.

An Introduction to Algebra from The Math League -- couldn't get more reputable than that.

Looks like a great site!
