**Course goals**

1. To review and master mathematical skills involving real numbers , order ,

absolute value, polynomials , and linear equations .

2. To further develop an understanding and working knowledge of

factoring , the rectangular coordinate system , linear relations, and

parabolas.

3. To introduce and provide a knowledge base of rational expression ,

rational exponents , radicals , complex numbers , quadratic equations ,

inequalities, symmetry, functions and their combinations , and linear

systems of equations in 2 and 3 variables .

4. To provide the algebraic background necessary for taking MTH 115,

Finite Math.

5. To develop problem solving skills in a mathematical setting.

**Evaluation**

Your grade will be based on the following percentage scale:

A+ = 97-100 |
C+ = 77-79 |

A = 94-97 |
C = 73-76 |

A- = 90-93 |
C- = 70-72 |

B+ = 87-89 |
D+ = 67-69 |

B = 83-86 |
D = 63-6 |

B- = 80-82 |
D- = 60-62 |

60% of your grade will be determined by 2 take home tests.

40% of your grade will be determined by 7 closed book quizzes.

**Suggested problem sets will be handed out at each**

class.

**Course Policies**

It is very important that you attend all classes. In the event that you should
