*Course Number*

MA:108A

*Credit*

4 semester hours

(Not all colleges will freely transfer this course.)

*Prerequisite*

There are no specific prerequisites for this course.
However, appropriate placement on the ASSET placement test
is required.

*Description*

In Intermediate Algebra students will review, refine, and
expand their skills with solving equations, working with
polynomials, graphing, and applying mathematics to outside
situations. The use of technology (especially __ graphing
calculators__) as a tool for problem solving is
heavily incorporated into this course.

*Schedule*

Monday nights, 6:05-10:00pm, All ILCC Centers (via TV
system)

The course originates from Emmetsburg.

*Overall Goals*

- Differentiate the sets of numbers, and explain their properties.
- Solve linear equations in one variable.
- Simplify mathematical expressions.
- Use matrices and determinants to solve systems of linear equations in two and three variables.
- Factor polynomials, and solve polynomial equations.
- Graph linear equations and inequalities.
- Solve rational, radical, and exponential equations by reducing them to polynomials.
- Select and use appropriate features of graphing calculators.
- Apply appropriate rules of mathematics to solve real-world problems.

*Book*

Hubbard and Robinson. *Elementary and Intermediate
Algebra: Discovery and Visualization*. Boston:
Houghton Mifflin, 1998. This is a new book, selected this
year by the full-time members of the math department
faculty. It is available through the ILCC bookstore.

*Calculator*

A GRAPHING
calculator is required for this class. Examples in the
book are geared to the TI-82 or TI-83 graphing calculators.
Calculators with lower numbers (TI-80 or TI-81) may not
have all the necessary features. Higher numbered
calculators (TI-85, TI-86, or TI-92) will have the
necessary features, but they may be more difficult to use.

TI-82s are available for $60 - $70 in stores such as K-Mart or Wal-Mart. TI-83s normally cost $70 - $80 in discount stores. You may also wish to check with area high schools, which may have bulk purchasing programs available in the fall. High schools may also have used calculators available, at prices less than half those of new models.

*Other Supplies*

You will want a large supply of notebook paper--to take
notes in class and to complete assignments. On a couple of
occasions you will find a limited supply of graph paper
useful. (You may wish to join together with another
student, so neither of you needs to buy a full packet of
graph paper.)

*Assigments*

Each week you will be given an assignment that includes
both "suggested" and "required" problems. We will go
through the suggested problems in class the following week.
The required problems will be due on each test date. All
required problems together will be worth the same as one
test. While correct work is necessary for full credit, answers and hints to the required
problems will be given on this page throughout the
semester.

*Tests*

You will have four tests over the course of the semester.
The tests will be graded on a straight point basis, with
90%+ = A, 80%+ = B, 70%+ = C, 60%+ = D, and 59%- = F. The
tests and required assignment grades will be averaged to
determine your final grade in the course. Tests and
assignments will include "+" and "-" markings, but these do
not appear on ILCC
grade reports or transcripts.

*Attendance*

You are not specifically graded on attendance, but you
alone are responsible for completing the requirements of
the course. If you are absent from all or part of a class,
you should see another student to be sure you have that
night's notes and assignments. All assignments are due on
the dates specified. If you can not be there that night,
you should turn it in BEFOREHAND. It is assumed you will
take tests when they are scheduled. If this is impossible,
you must see Mr. Burrow to schedule an alternative.

Test and assignment due dates will not change, unless class should be cancelled due to weather or some other unavoidable reason. However, topics to be covered are tentative and may change somewhat as the semester progresses.
