COURSE DESCRIPTION

The tools of algebra are required anytime we want a precise answer to questions such as How many..?, How much..?, How big..? Math 90 is a fast paced course reviewing these tools and preparing you for a more advanced intermediate algebra course such as Math 103 or Math 110. During the coming four months you will study variable expressions, linear and quadratic equations, inequalities, graphing concepts and systems of equations. To succeed in Math 90 you will need a good background in the basic math operations such as multiplication, division, addition, subtraction and fractions. Math 88 is offered for those individuals who consider themselves weak in these fundamental areas.

COURSE OBJECTIVES

By the end of this course you will know how to manipulate the constants and variables in an algebraic equation to solve for an unknown quantity, to create an alternate equation or to make a graph of the equation. You will become familiar with uses of scientific notation and with operations on exponents. And you will learn several methods of solving quadratic equations. You will find the skills learned in Math 90 to be invaluable as you move on through the more advanced courses needed to obtain your degree.

COURSE MATERIALS

Text Book        " Elementary Algebra", 8th edition by Bittinger & Ellenbogen

                                    Purchase at Cuyamaca College Bookstore.

Class Notes:   Class notes may be downloaded from my Cuyamaca Website; www.cuyamaca.edu/jim.christensen/

Lab MathXL:    You will need to purchase a MATHXL ACCESS CODE to participate in the lab. This access code will come with the book if you purchase the book at Cuyamaca. Otherwise you must purchase the code separately.

Calculator:       A Scientific Calculator is required. In addition to the usual math functions your calculator must do square roots, scientific notation and numbers to arbitrary powers. I can help you with the TI calculators; you are on your own with anything else. Cell phones and other types of communication devices are not an acceptable substitute for a calculator.

The TI-30x or TI-36x are very good inexpensive scientific calculators suitable for the purposes of this course and I urge you to purchase one of these calculators.

COURSE WORK

Completing the course successfully involves satisfactory performance on tests, quizzes, homework, group work, and computer lab work. This 5-unit course requires at least 10 hours of homework per week. If you cannot spend at least this amount of time on your homework, RECONSIDER your plans and priorities. You are expected to attend class fully prepared with your textbook, notebook, pencils, eraser and calculator. Pens should not be used for math.
