Math 0901 Basic Algebra
SelfGuided Review of Algebra
This is the website containing the materials I used when I taught Math 901 at UMM fall 2009. If you wish to review algebra over the summer with the intent of retaking the math placement exam and starting in precalculus in the fall, you can use the materials on this website to structure your review.
You can buy the text to have additional problems to work on and additional explanationsbut that is NOT absolutely necessary: you can use the purplemath website and Notes and Examples below as your text. You can do the homework problems, the practice tests, and read purple math and my course handouts for more information.
My advice would be to look over the Notes and Examples for each topic, practice with some of the Homework Examples, then try the Practice Test. If you feel you need more practice, work through some more problems from the Homework Examples (the Homework Examples show the steps of the solution, whereas the Practice Tests just have the final answer). Your goal is to be able to answer all the question on the Practice Test correctly without using any notes or aids other than a calculator (and ideally you would rarely use the calculator).
Most people learn math best in a cyclical mannerwe learn something, forget it, relearn it, and continue that process. With each relearning the concepts should come back to you quicker, and ultimately you will master the concepts (meaning you can use the concepts at will, when needed, to solve problems). Do not be afraid to look back at previous units for a refresher if you need to!
One final note: you may have learned alternate ways to solve some of these problems. Feel free to use the techniques you are comfortable with even if they are not the techniques I suggest here.
