### Revised Course Description

MAT 003 covers real numbers, ratio, percent, exponents, variables, basic algebraic expressions, graphs and solutions of linear equations and inequalities, equations and graphs of lines, polynomials, applications.

MAT 003 meets for three hours of lecture per week. It is a pre-collegiate course. It is graded on a CR/NC basis and does not count toward the Bachelor's degree.

### Prerequisites

MAT 003 has no prerequisites.

### Textbook

Introductory and Intermediate Algebra (2nd ed.) by Lial, Hornsby, McGinniss, published by Addison-Wesley. Chapters 1-6.4. (The rest of this text is covered in MAT 009).

### Objectives

After completing MAT 003 the student should be able to

• substitute positive and negative integers, rational, and real numbers into arithmetic and algebraic expressions involving variables, parentheses, positive and negative exponents, ratio and proportion, percent, and absolute value, and correctly evaluate the result;
• transform linear expressions into equivalent forms and solve linear equations and inequalities in one variable;
• solve systems of linear equations and inequalities in one variable using both graphical and analytic methods;
• use and understand function notation in the context of linear functions, graph lines, understand slope, find equations of lines given initial conditions (two points, a point and a slope, etc);
• add, subtract, and multiply polynomials;
• reformulate practical problems in algebraic language and apply algebraic techniques to solve them using the correct units (inches, kilograms, etc.);
• produce clear, concise, and correct written arguments showing the steps used in manipulating algebraic expressions and solving algebraic problems.

### Expected outcomes

Students should be able to demonstrate through written assignments, tests, and/or oral presentations, that they have achieved the objectives of MAT 003.

### Method of Evaluating Outcomes

Evaluations are based on homework, class participation, short tests and scheduled examinations covering students' understanding of and skill in basic algebra, exponents, ratio, percent, absolute value, linear functions, graphs, solving equations, applications to practical problems, mathematical writing, and related topics that are covered in MAT 003.

Grades in MAT 003 are based on homework, tests, a final exam, and class participation and attendance, in the following proportions.

 Homework, attendance, class participation, quizzes, etc. = 15% of grade 1st Midterm = 18% of grade 2nd Midterm = 18% of grade 3rd Midterm = 18% of grade Final exam = 31% of grade ---- 100% of grade

The grading policy regarding homework, class participation, attendance, quizzes, etc. is the following: 5% of the grade is determined by attendance. The remaining 10% of this portion of the grade will be determined by 5 to 10 minutes quizzes. These will be given in principle every Tuesday, and will contain problems similar to the problems from the homework of the previous week. This is the most important component of the course because students who study hard, do their homework correctly and on time, attend class regularly, and participate actively in class do well on midterms and exams and can expect to pass the course. Students who fail in one or more of these areas will do poorly on exams and fail the course.

Midterms and the final exam are produced by the math department and are common for all sections of MAT 003.

### Make-up Exams

The math department does not generally provide makeup exams for students who miss regularly scheduled exams. It is the student's responsibility to make whatever arrangements are necessary to ensure that he or she is able to take exams at the regularly scheduled place and time.
